Re: [exim] Slow SMTP

Hi guys

This is interesting stuff
I do indeed use a different port for my SSL connections but not 587
I use 465 which I was reliably informed on this list is the (now) generally
accepted port for SSMTP

So I could use something like the config below. However, correct me if I am
wrong does this config not set the addresses for which the check WILL be
performed i.e. wouldn't the if statement still cause the delay

Would it not be better to have something like

rfc1413_query_timeout = ${if eq{$interface_port}{465}{0}{30}}

not sure if I need the "!" in the last set of parentheses? Like so ...

rfc1413_query_timeout = ${if eq{$interface_port}{465}{0}{! 30}}


or (this is a guess) does the "!" mean "anything but" ?

Kind regards

Hill

received_port. I use:

# We'll try and avoid RFC1413 lookups for client connections on
# the MSA and SMTPS ports.  Ideally this would be done by setting
# rfc1413_query_timeout to zero for such connections.  However this
# variable isn't expanded.  So we'll set rfc1413_hosts instead.
rfc1413_hosts = ${if eq{$received_port}{SMTP_PORT} {*}{! *}}
rfc1413_query_timeout = 15s
