Wondering what people recommend for SMTP mailers, besides sendmail. I initially wanted to use sm, but I'm finding it's queue functionality doesn't work too good for my application.
I need to be able to do my own queueing and status management based on the regular STMP protocol parsed and interpretted on stdout. Sendmail tries VERY hard to queue stuff, as it should. As such, it's not a good candiate for me.
I thought about using qmail or exim, but both seem to also be queue-centric. I also saw serialmail, but it requires an external SMTP host to do the mailing (which won't really work for this either).
I need something that can talk SMTP, and understands how to interpret MX records from DNS lookups, but doesn't queue. It either works, or it doesn't, and it can dump the associated error messages to the screen -- mailbox full, host unresolveable, no mxrecord, host not responding, etc...
