I am experiencing issues with emails from my internal server using the Astaro as a relay host.
Some messages have been waiting for up to 3 days in the queue of my internal mail server.
I haven't been able to find the cause, only the effects. The message is released for the mail server queue and sent to the Astaro. After the header is accepted by the ASG, the message body times-out.

2009-06-21 21:32:06 1MILCU-00031r-0v SMTP data timeout (message abandoned) on connection from mail.internal.mydomain.net [172.16.0.8]:37354 F=
My mail server is a strait postfix server (v 2.5.1), that has been running for a few years without a problem and with older versions of the ASG without any glitches.
Steps I have tried:
- Triple checked all my SMTP configuration settings on the ASG as well as the internal mail server.
- Restarted postfix on internal server, even rebooted out of desperation.
- retried multiple times to release the queues from the internal server, same message every time.
- restarted SMTP daemon on the ASG
- finally also rebooted the ASG
Solution:
- I bypassed the relaying to the ASG and the messages were all sent successfully.
ASG Configuration:
- Nothing special there, the internal server is allowed to relay.
- Domain signing is disabled.
- Scan relayed (outgoing) messages is disabled.
- Encryption is enabled but only one user.
Has anyone experienced similar issues ??
