I've got sendmail running on my ibook, and it works great on my own domain. at work today i tested it and it seemed like it didn't work, though i attributed it tonight to a poor .cf file (my bad). i wonder if anyone knows how to set up sendmail to run regardless of what network it's on...the idea being its own MTA, so I can wander around without having to relay through another SMTP.
do you have to add _every_ network you're on, or will ever be on, to achieve this? or can one simply send mail through localhost without such heavy-handed editing?
