Postfix problem receiving the initial server greeting

[Samp]

I got this morning this error message in mail.log :

status=deferred (delivery temporarily suspended: conversation with zimbra.geismar.com[88.191.228.37] timed out while receiving the initial server greeting)

What's wrong.

How about DNS problem, network problem, firewall problem, one of the ZImbra services not running or something similar to those problems - you should investigate those problems first. Try and telnet to the server by FQDN & IP address and see if you get any problems.

BTW, when you post errors messages from the logs it helps to post more than just the error line - sometimes the significant detail is in the surrounding messages.

I tested DNS, network, firewall, after restating zimbra that's work fine and after several minutes the problem come again !?

At this time no more mails are sent, same error message, I have to restart Zimbra

[Samp]

...perhaps it's the to many open files problem, I add il /etc/security/limits.conf:

zimbra soft nofile 65535
zimbra hard nofile 65535

And restart the server.

Wait and see...

Now sometime I got this message:

status=deferred (delivery temporarily suspended: lost connection with zimbra.geismar.com[88.191.228.37] while sending end of data -- message may be sent more than once)

Lot of problem after system upgrade (Debian 6.0)

Hi,

I always got the same problem, after restart Zimbra the mail work fine, then after several minutes I got:

status=deferred (delivery temporarily suspended: conversation with zimbra.geismar.com[88.191.228.37] timed out while receiving the initial server greeting)

In the same time I got in mailbox.log:

In the first instance, the sending mail server is on at least one RBL:

http://www.uceprotect.net/rblcheck.php?ipr=88.191.228.37

Is this a VServer by any chance?

All the best,
Mark

Not the server itself but the isp's network 88.160.0.0/11 and only in uceprotect level 2

And what about my problem ?

Did you think is right to charge 150 Euros to delete network from list ?

(see attached image)

Yes, if that's what they want to charge. You didn't mention that the €150 is for Express de-listing and there's a free option where you wait for that to expire and the affected IP is removed. What you should do is investigate why that IP is on the blacklist and fix the problem so it doesn't happen again.
