How do I deliver an email stuck in my Postfix mail queue?
9,033
postqueue -f
is generally used to flush the queue, after the root cause of the delivery failure is solved.
-f Flush the queue: attempt to deliver all queued mail.
This option implements the traditional "sendmail -q" command, by
contacting the Postfix qmgr(8) daemon.
Warning: flushing undeliverable mail frequently will result in
poor delivery performance of all other mail.
postqueue -i
can be used for a specific message:
-i queue_id
Schedule immediate delivery of deferred mail with the specified
queue ID.
This option implements the traditional sendmail -qI command, by
contacting the flush(8) server.
This feature is available with Postfix version 2.4 and later.
If you have a permanent IPv6 outage, you may disable IPv6 in postfix with inet_protocols
.
From http://www.postfix.org/IPV6_README.html :
/etc/postfix/main.cf:
# You must stop/start Postfix after changing this parameter.
inet_protocols = ipv4 (DEFAULT: enable IPv4 only)
inet_protocols = all (enable IPv4, and IPv6 if supported)
inet_protocols = ipv4, ipv6 (enable both IPv4 and IPv6)
inet_protocols = ipv6 (enable IPv6 only)

Chloe over 7 yearsThanks, that worked! It was set to
inet_protocols = all
. Now it sends:Jan 18 16:49:04 ip-172-31-15-65 postfix/smtp[6461]: C71C42026D: to=<[email protected]>, relay=alt2.aspmx.l.google.com[173.194.219.27]:25, delay=1.6, delays=0.65/0.09/0.24/0.64, dsn=2.0.0, status=sent (250 2.0.0 OK 1484757944 x4si232979ybh.76 - gsmtp)
