Re: Spamming over hMailServer

By the way I've just realized from logs that many of our mails getting this error (451) even if they're coming thru SMTP. Here is a sample log that I've sent from my Yahoo! mail to my hMailServe account: "SMTPD" 3720 258151 "2010-02-09 18:29:46.656" "98.137.27.133" "SENT: 250 OK" "SMTPD" 3720 258151...

Limiting usage on account basis

It would be nice if we're able to limit users (a general setting for all domains is a must I think but ability to specify accounts for the rule may be a plus) on some criteria like; * max number of messages per time unit (e.g. an account should not send more then 100 mails in a day) * max number of ...

Re: Spamming over hMailServer

Re: Spamming over hMailServer

Hi Doom, Thanks for the advices. I'm sure we do not have any scripts sending w/o authentication. We always add SMTP authentication to codes. By the way the other information is so critical. Yes we have an webmail-end (squirrel) installed on same server. So I'll take care of that once we migrate. Bes...

Re: Spamming over hMailServer

Hi Doom, Be sure several backups will float on the server :) We plan to perform another update on server on Monday night. If I can make managers accept, we can perform this update with the other one. I pray, you or some other experienced hMailServers-angels will be online if we live problems during ...

Re: Spamming over hMailServer

Ok, now considering the update with my technical team.

Is there an side-effect? Or anything we need to do before/after upgrade? Are there any known problems?

Thanks all for your help,

Re: Spamming over hMailServer

Ok, all values are 0 in tarpitting and I'll not bother with that. I'm not sure about "auto-ban". What's it and how can I activate it? By the way we're using 4.4.1-B273. Do you suggest an upgrade? Is there a better protection about any issue? Are there any pitfalls during upgrade? Because many custom...

Re: Spamming over hMailServer

I understand the status about passwords... I've already restarted server after changing the password. At the moment everything seems to be going well on server. There is no abnormal activity. By the way I want to ask something about "tarpitting" option in Spam Protection section. After the problem w...

Re: Spamming over hMailServer

Hi martin, Thanks for quick response. I've changed the password of that account. Now I'm watching server activity. I'll let you know after a few hours whether everything is normal or not. By the way, is there a way to find out the weak account passwords in hMailServer to prevent this? Passwords are ...

Re: Spamming over hMailServer

Hi mattg, I stopped for a while and searched but nothing changed. I've managed to stop the abnormal activity by disallowing empty senders. I do not know what side-effects will strike but no abnormal activity at the moment. I have a "You have configured hMailServer not to allow email with empty sende...

Re: DNS Problem

Hello ^DooM^, Thanks for ultra-fast response. You seem to be right, we've directly judged ourselves instead of first checking the mx records of target domains. After testing many of domains manually, I realized that you're right and they do not respond with an expected answer. But these records seem...

DNS Problem

Hi, I'm the manager of a Turkey-based software development company. We've switched hMailServer 4.4.1-B273 for our clients. We have about 150 domains hosted. After we completely moved our mail accounts, we began to live weird DNS problems. After I read a lot of topics in this forum, I'm nearly sure t...
