Hi. I've just migrated an e-mail server with about 300 users over to iRedMail. Most mailboxes seem well, but some users are not receiving e-mail and in /var/log/mail.log I see this entry each time one of the problematic mailboxes is supposed to receive an e-mail:

Jun 28 13:37:45 s7 postfix/pipe[19601]: 8B6155B261: to=<(EMAIL_ADDRESS)>, relay=dovecot, delay=943, delays=943/0.05/0/0.05, dsn=4.3.0, status=deferred (Command died with signal 6: "/usr/lib/dovecot/deliver")

I've enabled Dovecot debugging but as far as I can see nothing is actually getting written to /var/log/dovecot-*.log...

This is weird, usually Dovecot will log to /var/log/dovecot*. Did you enable all debug options?
FYI: http://www.iredmail.org/docs/debug.dovecot.html

I had these debugging options enabled;

mail_debug = yes
auth_verbose = yes
auth_debug = yes

I'll try enabling all of them.

Re: Command died with signal 6: "/usr/lib/dovecot/deliver"

About half an hour later and still nothing has been logged.

root@s7:/var/log# doveconf | grep 'debug\|verbose'
auth_debug = yes
auth_debug_passwords = yes
auth_verbose = yes
auth_verbose_passwords = yes
debug_log_path = 
mail_debug = yes
verbose_proctitle = no
verbose_ssl = no

Could it be the fact that debug_log_path is empty?

Only 3 parameters are enough:

mail_debug = yes
auth_verbose = yes
auth_debug = yes

Did you change any setting in /etc/postfix/master.cf?

Nope.
