Zimbra Troubleshoot: Postfix/Postdrop Permission Denied

I was working on upgrading Zimbra version. After upgrading the Zimbra package, I found an error like below while checking Zimbra log.

Error:

Apr 29 21:34:46 hmail postfix/postdrop[24236]: warning: mail_queue_enter: create file maildrop/808948.24236: Permission denied

Solution:

I solved it by executing below commands.

zimbra@mail:~$ postfix stop

/postfix-script: stopping the Postfix mail system

zimbra@mail:~$ killall postdrop

zimbra@mail:~$ postfix start

/postfix-script: starting the Postfix mail system

 

I again checked the Zimbra log and error has been disappeared.

We received some complaints from one of our customers regarding problem of sending email, especially rate limit, to Gmail. After some diagnosis, we found that the users keep 70-80 email addresses in TO/CC/BCC. In order to restrict users to send emails on such accounts at a time, we implemented a policy. After executing this policy, users shall not be able to add more than 10 email addresses in a message. root@mail:~# su – zimbra Check the current limit: zimbra@mail:~$ postconf | grep smtpd_recipient_limit  smtpd_recipient_limit = 1000     ##This is the default recipient limit zimbra@mail:~$ postconf -e 'smtpd_recipient_limit = 10'   It will restrict the recipient limit to 10.
