"[..] cause sendmail to use the resolver options defined by the ResolverOptions option, except that it always enables DNSRCH when doing lookups with the $[ and $] operators."

...except I'm dealing with an ancient system where /something/ in the resolver is broken when sendmail walks down the search path for a domain that's unresolvable in the recipient list of a mail. (Not sure why it even checks those when it's the fnal destination for the message.)

@galaxis For a program called sendmail it's surprisingly difficult to get it to send mail


@ifixcoinops In this case it's about receiving, and a 12 year old OS underneath certainly doesn't help things...

All in all, it's still my favourite general-purpose MTA.
