Hello!
I try to understand different mail delivery times.
I have a script (phpmailer) that sends 500 mails to a remote mail
server. The target address is a local /dev/null mailbox. The script
uses SMTPKeepAlive = true; to keep the connection open.
If my client IP is part of mynetworks the time for 500 mails is about
29 seconds.
If I use AUTH (SASL via Dovecot) the time is about 47 seconds. It
doesn’t matter if the connection is protected with STARTTLS or not.
The encryption isn’t the problem.
Did you test by changing the value of $mynetworks and using the same
source machine or are the SASL and $mynetworks sources physically
different machines?
As Wietse said, this could be as simple as machine physical location and
the value of c. It also could be subtle differences between the machines
used which may not even be visible to you if both are virtual.
