zimbra system user bounced on mail each night at 2:00 am

Postby ludolelarge » Fri Jun 23, 2017 8:44 am

Dear all,

I recently installed zimbra Release 8.7.9.GA.1794.UBUNTU16.64 UBUNTU16_64 FOSS edition.

It working fine, but nightly at 2:05 am, i have a bounced mail in my log from system account zimbra. <zimbra@mail.eta123.be>, this account doesn't exist.

here's my log :

/opt/zimbra/libexec/zmmsgtrace -s zimbra@mail.eta123.be /var/log/mail.log

Message ID '20170623000521.658091C13A8@mail.eta123.be'
zimbra@mail.eta123.be -->

Recipient zimbra@mail.eta123.be

Solved !

backup mailbox script in crontab generate mail.
solved by adding >/dev/null 2>&1 in crontab.

You can also likely fix it, and still get the emails by adding

MAILTO=anAccountThatExists@your.domain
MAILFROM=anAccountThatExists@your.domain

as the first 2 lines of the zimbra crontab. This will send the email from the MAILFROM account to the MAILTO account.

They should be inserted before the lines
# ZIMBRASTART -- DO NOT EDIT ANYTHING BETWEEN THIS LINE AND ZIMBRAEND
SHELL=/bin/bash
