Our customer are facing problem with mail delivery...mail delivery is taking around 1 hour... in defered queue i found more than 2000 mails regarding over quota....!!
and in avtive queue ..more than 40 mails r in queue..
I searched this issue in forum...and set below setting as per suggestion to bounced back mail if mailbox is full :
zmprov mcf zimbraLmtpPermanentFailureWhenOverQuota TRUE
And its working...but the message format is :
email@example.com>: host mail.example.com[PRIVATE IP ADDRESS OF MAIL SERVER] said: 552 5.2.2
Over quota (in reply to end of DATA command)
So in this mail its showing proviate ip address of mail server next t odomain name....how can we remove that ?
IS there any other stuff i need to check if mails are getting delivered late ??
