Re: Need Advice

Does it show why delayed with command 'postquque'? for example:

# postqueue -p | head

Re: Need Advice

yap.. using :

# postqueue -p | head

or

# mailq

and I also check the email transactions, it show the email delay 1666 second or 28 minute. for example in this case :

================================================================================
Email receive into mail server :
Jul 23 09:58:40 mailserver3 postfix/qmgr[30670]: 6AF14606BA: from=<a@xxxx.com>, size=3325, nrcpt=515 (queue active)

Email delivered in user (POP3)
Jul 23 10:26:20 mailserver3 postfix/pipe[25249]: 6AF14606BA: to=<b@xxxx.com>, relay=dovecot, delay=1663, delays=3/1632/0/28, dsn=2.0.0, status=sent (delivered via dovecot service)
================================================================================

could you help or any suggestion to solve this issue ?

Thank you.
