I updated to B300, and didn't notice right away but there seems to be a problem. No errors sending emails out to HMS, and apparently messages came in, but couldn't be locally delivered into the accounts. After trying to figure out why I wasn't getting emails I was sure I should have. This error is i...

Just off the top of my head, you can compile your .NET script into a console EXE, and shell to it from the event handler, passing the arguments. Not too pretty, but could be worse!

Blue Ninja

Why not just import a reference to the hMailServer COM component into your .Net project, and use it? COM interop is supported, so nothing needs to change in hMailServer to use it from .NET. As for the future - well, it's always changing. "The future is OLE!" became "The future is ActiveX!", which tu...

Blue Ninja

Hmm, good point - that would be recommended!

Blue Ninja

Support in the service and database should be easy anough, as well as the COM API. I think the part that will be most difficult is the Administrator program - VB6 handles Unicode perfectly in strings, APIs, and everywhere else - except in the Windows Froms controls. So howing them properly in text b...

Thanks Martin, I understand. I had thought the purpose was to stop exactly this type of attack, using non-compliant mail sending scripts - there's already a setting for max recipients. I am definitely interested in seeing an enhancement to this feature, whereby it forcibly disconnects naughty client...

Martin, Whilst looking through my log today, I saw the following: "SMTPD" 22024 505 "2007-03-27 17:43:27.937" "67.11.227.206" "SENT: 220 mail.blueninjasoftware.com Welcome to Blue Ninja's SMTP server.

I disagree with this. From a historical point, we used to have only UUCP available. TCP/IP was designed to operate with ony part-time/flakey connections. To require every one to have a full-time, five-nines, connection-or-they-are-spammer is retarded, stupid, arrogant, and annoying! It goes against...

Blue Ninja

Haven't thought about it much (and admit I haven't even read the entire thread), but I have a hard time seeing that forcing email senders to adhere to specifications for email sending could be seen as "breaking". With your law-changing-argumentation, wouldn't the appropriate action for you be to tr...

I can't help but strongly advice against running business e-mail services behind connections of which you cannot organize a simple thing as reverse DNS. For home experimenting it's fine, but expect to be on several black-lists or having your e-mail marked as spam. I agree with you, to a point. Cert...

Blue Ninja

If your provider does not provide any kind of reverse DNS, they're incompetent, and you should consider changing provider. On one hand, I agree with you - if a provider doesn't do their job properly, you should dump 'em and get someone better. But from a practical standpoint, that's nearly impossib...

Blue Ninja

Where would the desired language information come from? Nothing in the SMTP protocol identifies a preferred language, though even that would be of the connected mail server, not the end-user. So how would hMailServer know what language to send the DSN in? I am not aware of an accepted-languages head...

Blue Ninja

I am 99.44% certain I had postwed a feature request for this previously, but am in a bit of a rush at the moment, so I'm not going to search for it now.

Either way, I second the notion!

Blue Ninja

Why not simply require authentication for deliveries? If the user has a valid POP3 account, they can use those credentials for SMTP. This might be a better approach than doing the POP3 connection simply to prove authentication, then doing SMTP unauthenticated, no?

Blue Ninja

What about people who use their domain's catch-all accounts? I don't want to setup a wibble@mydomain.com account or alias just so I can send email. I might want to have that wibble mail redirected to my catch-all ("junkmail") account. Not saying that this isn't a great idea; just presenting a possi...

Blue Ninja

SPF would deal with that sort of spam but if you haven't setup SPF that would be a welcome addition. Good point - i *do* have SPF set up, but in the SMTP logs, it seems that greylisting takes precedence over SPF lookups. Perhaps this should be done in another order? Why grey-list stuff you already ...

Blue Ninja

I see that a lot of spam uses a "From" address that appears to be the same domain as the "To" address. Since hMailServer knows all valid accounts and aliases for it's own domains, I suggest that any incoming mail to be delivered locally with a "From" address that does not exist be either rejected or...

After some rebooting yesterday due to other configuration issues not related (that I can tell) to hMailServer, it is now listening on both addresses. Not sure what it was, but I'll go with the assumption that it was not an hMailServer issue for now, as I noticed some other odd things as well. But if...

Blue Ninja

Hmm, I didn't see any errors, and I can see both from telnetting, and from my website no longer sending emails, and from my firewall that only my static IP is actively listening for that app and 127 is not. It might be related to some other oddball configuration issue though, I'll try to poke around...

Blue Ninja

Martin, Well, that's good news - your explanation is exactly how I *thought* it was supposed to work. However - I have my static IP in the "SMTP" settings to bind to, and in my Multi-Homing settings, I have my static IP as well as 127.0.0.1. hMailServer is only listening on my static IP though, not ...

Blue Ninja

That seems to be how it works. I recall this feature being added after much begging, because the outgoing SMTP connection would grab whatever my "default" IP was, and that would often cause SPF to fail, as the mail wasn't from the IP it should have been from. So, I requested the ability to bind to a...

Blue Ninja

I have both my pblic static IP address and my 127.0.0.1 address as IPs to listen on in my Multi-Homing settings. In my SMTP configuration, I have "Bind to IP address" as my public static IP - this was because sometimes hMailServer would use one of my other IPs to send from. I recently diagnosed a we...

People who sink low enough to even LOOK at a MySpace deserve everything they get - kinda like you don't feel bad for a guy who gets some nasty disease from a cheap whore house

Blue Ninja

Ok, I think I see how you plan on using it now. It might not be useful to everybody, but for those to whom it would be, it would be pretty helpful!

Blue Ninja

What exactly is it you wish to whitelist here - the IP address, or the sender address? Based on the problem you describe, whitelisting the IP wouldn't help, because your ISP uses any number of mail servers to send. So if you whitelist an IP in the "Greylist queue", then the mail may be re-sent using...

That's odd, the multihoming IP list works fine for me in build 248. I tried adding/deleting another IP to the list to test it, and it seems to work with no problems. I use MySQL 5.0.24a.

Blue Ninja

Martin, I've been using Mantis for a while now, and it has a "Sponsorship" feature where users can sponsor features for some amount of $, which you can track and manage. Might be a handy idea, no?

It seems pretty easy to integrate into various other things, might be worth a look!

Blue Ninja

So there should simply be a list of IP addresses called 'forwarding relays'. And when a message is received, hMailServer should locate the first IP address in the Received addresses which is not in the list of forwaring relays, and then do spam protection using that one. Correct? Yes, I believe tha...

Blue Ninja

I understand what you ment. But are you sure that using greylisting increase the delivered spam? Does a majority of the spammers really follow the RFC's and first try the primary server and then the secondary server? I don't know... I thought, if anything, they tried the backup server first.. Well,...

As a developer, I know begging usually doesn't help much. At least when it's not in person :-) I have read that link, and have the request posted in the appropriate forum.

I've noticed something. In another post , I mentioned having problems where legitimate email cmoing through my backup MX (I'm using DynDNS's Backup MX service) was getting flagged as spam because the SPF checks against the backup MX server, not the previous sender. I was wondering why so many legiti...

The SPF / Backup MX feature needs more votes, too

http://www.hmailserver.com/forum/viewto ... 7643#37643

Blue Ninja

I agree that this feature would be useful, but why are you not checking for spam on your backup email server as well? I found a lot of spam is purposefully sent to my backup mx server as a lot of backup servers are less protected for spam and deliver straight to the mailboxes of their victims. As s...

Blue Ninja

Just wondering if this is implemented yet? I notice that hMailServer tags some incoming emails as spam as the result of SPF failure, and the commonality of these is that they all came through my backup MX (not sure why, as my primary is always up). I used to need the relay because my port 25 was blo...

I'm have nothing but praise for grey listing. Here at least it is stopping about 99% of all spam. Just a note, You can think of grey listing as a temporary means of slowing the spammer down, that is until they get listed on the many DNSBL, then the BL will take over. From my experience's most spamm...

Blue Ninja: The SMTP protocol is fine. SMTP is designed to allow delivery of messages. It meets that goal. Obviously custom client-server apps with binary transfers are more effecient at transferring large files, but they do not meet the same criteria that SMTP does. That is hardly something worth ...

Blue Ninja

The first sentence was me bitching about email being a text-based protocol, which IMHO is ridiculous since it sends an awful lot of binary data, which needs to be MIME-encoded, which in turn wastes a lot of space and bandwidth. I'm one of those binary protocol guys - nearly all my client/server apps...

Blue Ninja

Since I still get several hundred spams per day, I started looking at what (besides totally rewriting the outdated and ridiculously stupid system of can't-even-handle-binary-data mail currently used - SMTP) with something better. Anyhow, I notice that there are LOTS of entries in my greylist table f...

Hmmm... But will it bind to a specific outgoing IP address? That's the big question for me!

I suppose a belated 4.3 will still be acceptable

That because today is my birthday, Martin was releasing hMailServer 4.3 - has anyone else heard this?

You'll see where I donated as an attempt to "sponsor the feature" (readL "bribe Martin to hurry up with it"), but his response was that a bribe only works if I make him agree to it BEFORE making the payment. So maybe give that a shot...

I was just looking for a "Donate" link, hoping that sponsoring the feature would help prioritize it, but I see that's no longer needed :-) However, the program is still very worth it, and maybe it'll get 4.3 in my hands a day or two sooner than it otherwise would have? Haha! Seriously though, where ...

Well, it's seemed easy to implement using either the Winsock control (way back in the day) or the Socket classes in VB, by simply specifying the local address before making the connection - so I'm just assuming that for a seasoned C++ programmer like yourself (A language I personally have only a lit...

If I could download a test version of option #1 this afternoon, I'd be pretty happy... ;-) I definitely think the first option is very important.

Youcould use your ISP's SMTP gateway, but that will prevent you from sending SPF-compliant mail, since your domain wouldn't match the ISP's domain. Though you could include your ISP in your SPF record, that would let ANYONE on your ISP's domain send mail "from you", so that would be a disaster. I'm ...

Blue Ninja

Many mail servers reject mail as probably spam when it's coming from a dynamic IP - I had the same issue. I ended up switching to a commercial account with a fixed IP address, but another solution you could use is something like DynDNS.org's MailHop Outbound service.

You're a stronger man than I, BigDave - I could not deal with someone like that! I've completely cut people out of my life for sending chain emails, or for refusing to stup saying "wht r u up 2" via IM

This should not be allowed - you've based your request on the assumption they are in control, in which case it takes them 20 seconds to create the MX record.
