That's right. It is non-standard, but it is commonly used and will be
with us for a while. 587 is the standard port however.

I don't think that would work. rfc1413_query_timeout doesn't appear to
be expandable. it needs to be a hardcoded figure. That's why I chose
rfc1413_hosts which is expandable and which is a list of hosts to
perform the lookups on. The config I provided basically said: If the
connection comes in on port 25, do the lookup, otherwise don't.

Nope. rfc1413_query_timeout takes a number "! 30" is a condition.
