The company that hosts the email addresses of the TO and the FROM rejected your forward due to your IP being on a SPAMHAUS list

You will need to contact them

I have port 25 AUTH blocked, so they wouldn't even had the opportunity to try at my server (on port 25 at least)

Is it possible to anyhow send out email from external address to another external address?

That is set in IP ranges

Don't do that to the internet IP range or you will become an open relay

ALSO, please realize that most recipient servers will see these messages as spam

You should read the technical knowledge section at the bottom of this page https://www.hmailserver.com/documentation/latest/?page=system_requirements From the questions that you are asking, it seems to me that you don't have the required skill set to run a mailserver You should either look for anoth...

mattg

ALSO, is python available to the windows USER that hMailserver runs under

mattg

Ah yep, so it is

hold up could be AV at either end, or firewall inspecting packets somewhere
I'd check the computers with the mail client installed, and check the antivirus settings on those

mattg

It could ALSO be the recipient server doing the scanning, of which you will have no control over

mattg

make sure username is in the form 'user@domain.com'

mattg

You need the 32 bit version of the dll because hMailserver 5.6.X and below are all 32 bit applications

Even if you use 64 bit MySQL, you still need the 32 bit version of the dll

(The error actually tells you that too)

mattg

It's forwarding of ALL emails, not just the ones POPd from elsewhere, if that helps

ie a message is received via SMTP and is forwarded, it will be forwarded EXACTLY 60 second later

mattg

With a mail client like thunderbird or Outlook using those account@domain + password credentials = yes

1 and 2 are related events If SpamAssassin times out, then no score is added to hMailserver.

If you are only using the 4G connection for availability and not capacity, my recommendation is that you setup the router for true active/backup, and only bring up the 4g nic when the primary route is compromised, like when some remote service is unreachable.

I really do not see what you are planning to do with this....such a waste of time and resources on the server simply use SpamAssassin (which does a better job checking DKIM anyway) and set scores accordingly SpamAssassin often doesn't respond in time, and hMailsevrer ignores the result If have a ru...

What about forwarding to the gMail account (in hmailserver) rather than getting gMail to POP3 it

mattg

I only have one server, and a Multi-WAN router

I can only set one greeting, hence the 'DOMAIN NAME'

mattg

Yes, if the original destination account is same domain and both are hosted on your hMailserver, the message won't be DKIM signed

mattg

I think I must have already asked the ISP to change the RDNS (it was the MX2 ipaddress)

My local host name is [FQDN]

my 1st ISP connection has a RDNS of [FQDN]
My 2nd ISP connection has a RDNS of mx2.[FQDN]

i can't have the same RDNS for two IP addresses can I??

mattg

Is that at the recipeint's mail server ?

If you have a gmail account send a message to that, they show good info on DKIM signing

I often get a rogue connection that seems to cause my hMailserver to generate a minidump

You may find this interesting.

That looks like a sender 'request' to force StartTLS, and not allow unencrypted connections.

I allow unencrypted mail from another server on port 25, but all client connections to my server must be encrypted connections, and that includes for mail submission

@PugzPOE
Why did you set the default domain as you have done?
You should probably remove that

mattg

On a older windows machine running an email client, using a Microsoft mail product (eg Outlook, Mail etc)

This should NOT affect the machine running hMailserver, as hMailserver uses OpenSSL

mattg

make sure that you use the SMTP envelope FROM and not the Message FROM

The SMTP envelope FROM is in the SMTP logs

ALSO, have you opened mail ports in your firewall, and forwarded them from your router
