Hi community,
on my customer's Astaro 8.305, I recently activated the Mail-Proxy functionality using SMTP-profile mode. Currently, there are two SMTP-profiles set up which are apart from routing settings quite similar.
Unfortunately, a very high percentage of incoming emails are greylisted, including those from my own mail server.
The smtp-log's entry for greylisted emails are something like that:
2012:07:04-14:27:34 srvfirewall exim-in[7134]: 2012-07-04 14:27:34 SMTP connection from [88.x.y.z]:48572 (TCP/IP connection count = 1)

Due to this issue, and deactivated greylisting in both SMTP-profiles, and now emails are coming, through.
Could anybody help me out with troubleshooting this problem ?
Thank you very much in advance.

Tobias
