Very slow sending email from RT

RT Users
1

I’ve got RT2.0.13 running on RedHat7.3 using a postfix MTA. It appears that
every time RT must generate and send an email (oncreate autoreply, reply to
requestor, etc) it takes a good minute for RT to send the email. If it’s a
reply to requestor, RT hangs for this minute after clicking submit. No other
actions appear to cause this hang. I’ve exhausted all my linux knowledge and
I’m not any closer to figuring this one out. Anyone see this before? Anyone
have some suggestions to where/what I should be looking at?

Not sure if this is of any importance, but this is a migrated RT
installation. I used to have rt 2.0.13 running on a FreeBSD box. Ran
flawlessly there. These hangs started after moving to a new machine.

My first inclination when seeing a “about a minute” delay involving
sending mail is to check your DNS setup, including reverse DNS.

Thanks for the reply. DNS all looks good. I had a lot of trouble with DNS
earlier due to the postfix RPM and it’s use of
/var/spool/postfix/nsswitch.com and hosts.
DNS doesn’t appear to be an issue at this point. Also, I get nothing in
maillog during the hang.

Are you running postfix chrooted? If so, make sure your
/etc/resolv.conf within your chroot is correct as well.

You can speed up RT’s mail sending performance by ensuring that your MTA
operates in queueing mode, rather than immediate delivery. Waiting for
DNS/remote mail machines is the MTA’s job, not RT’s.
