Hello all,
I have a strange problem I will try to describe, sorry for the complexity.
Our topology is as follows:
We have one relay server on the dmz that gets and sends all mail from and to the outside.
This server gets and sends all the mail from and to the astaro from the inside.
we use exchange servers 5.5 that sends all their mail to the asl and receives all the mail to it.
It looks like this:
Exchange5.5-->ASL5.202-->Outside MailRelay-->Internet.
Internet-->Outside MailRelay-->Asl5.202-->Exchange5.5
The problem is when the outside MR sends the mail to the asl.
On large volumes the astaro seems to not accepting it's traffic and the outside MR gets queued with over 1000 letters in a matter of 1 hour.
Now what we did is to relay all inside mail to the exchanges Directly and the outside mailrelay has emptied its queue within 10 minutes (over 680 Megs).
This is how we got that the problem is within the ASL.
Our configuration is checking for viruses, and Spam. No extension checking and no Expressions.
We also disabled the DOS because we saw errors about "more than 10 mails with no mail command".
Now the log is not showing any more messages except the "no host name found" but we read somewhere here that it is not really a problem.
Any ideas will be appreciated.
