Deferred Connection timed out only to some domains

[tdunk]

Hi

I have just moved Scalix to a new server. On the old server I had problems sending mails to hotmail users, but unfortunately the problem seems to exists when sending to other domains as well on the new server.

The odd thing is that sending to google.com and most other domains goes o.k., but I have at least 4-5 domains that all fails with the same errors all related to timeouts.

The errors in the maillog is:

Code: Select all

Aug 11 10:01:35 mail sendmail[7768]: m7B7tugB007762: to=<zzz@hotmail.com>, ctladdr=<root@mail.geniti.com> (0/0), delay=00:05:39, xdelay=00:05:39, mailer=esmtp, pri=120375, relay=mx2.hotmail.com. [65.54.244.40], dsn=4.0.0, stat=Deferred: Connection reset by mx2.hotmail.com

My mail server name is mail.geniti.com and the public address is 87.61.115.66.

When inspecting the mails recieved at gmail from my mailserver it looks like this:

I have a reverse DNS for mail.geniti.com and I have tried raising some of the timeout options for sendmails, but still the same result.

Any suggestions?

Thanks!

I'd talk SMTP to mx2.hotmail.com and mail.itfax.dk, to see what they have to say for themselves.

This isn't a Scalix problem...

Thanks.

I'm also suspecting sendmail or DNS to be the problem, but I havn't been able to find anyone with simular problems.

I'm running on 64-bit platform and 64-bit sendmail might be the problem, but on my old server I was running 32-bit and there I had the same problem hotmail accounts.

I have tried manually sending mails to the domains through "Mail" and it works. Also telnet on port 25 is ok.

It's really strange....

Finally solved the problem!

Firmware upgrade on the firewall made the problem disappear.

Thanks for any advice.

So was the issue with *your* firewall?
