Hi all,
I'm running centos 7.2 with postfix 2.10.1, installed from the standard
centos 7 repo which corresponds to rhel 7.
I'm using php mail to send mails which uses /usr/sbin/sendmail -t -i to
send the mail.
On my previous server centos 6 using postfix 2.6.6 the mail was
delivered nearly instant to the recipient, whereas on centos 7 with
postfix 2.10.1 the mail gets enqueued for ca. 5 minutes and is then
successfully delivered to the recipient.
I could not find any switch or configuration option within main.cf or
master.cf which made an difference regarding the mail sending delay.
It would be great if someone has a hint or a solution which re-enables
the instant delivery again.
Thank you for your help.
Regards
Dietrich
