Hey, my e-mail-server Postfix+Cyrus was running for over 7 days and suddenly I get this error 554 554 5.7.1 : Relay access denied (state 14) when I try to send or recieve mail. Postfix worked fine and nothing was changed. There is enough RAM and LoadAverage is 0.56. Any suggestions where to start investigating (Ubuntu LTS 10.04)? This is quite strange, if I restart the whole server the mails are fine again.

Thank you for your help

You mentioned that restarting the server resolved the issue... but for how long? – Skyhawk Jan 24 '11 at 0:09
Once the server was running for 90 days, now around 7 days. I am afraid that I need to do it more often =( – Lerikunus Jan 24 '11 at 0:12

Check mydestination:

# postconf | grep "^mydestination"

Postfix does't see itself as being destination for domain and rejects the mail

tells me > hash:/etc/postfix/mydestination | there are all domains I use listed with OK behind it. – Lerikunus Jan 24 '11 at 0:22
use postmap to refresh /etc/postfix/mydestination – osdyng Jan 24 '11 at 0:27
