After upgrading to M3 I have the following issues in the zimbra.log :
Jan 9 09:27:06 mvimap postfix/lmtp: D85C487063A: to=
, relay=mvimap.foo.com[192.168.0.8], delay=1, status=deferred (host mvimap.foo.com[192.168.0.8] said: 451 4.0.0 Temporary message delivery failure try again (in reply to end of DATA command))
Can anyone tell me what this means ?
Thanks in advance.
