Yeah, we opened port 587 yesterday, and I got access to a relayed box...
from which I can do exactly what I want to... but from my SBC connection
I still can't get through to 25 or 587, which means either my internal
setup or SBC is blocking 587... and I'm about 99% positive it's not
anything going on inside my walls.
Find and download 'lft' (layer four traceroute), and you'll be able
to determine what hop is dropping the port 587 packets.
Sometimes I love debian... apt-get install lft... :)
But I don't quite understand the output... it all looks good to me then
says failure at the end... (pasted at the bottom)
I talked to SBC and they're completely clueless... I've toyed with using
SBC's SMTP server instead, but that's another whole host of
authentication problems that won't work. I think it's time to start
looking into stunnel.
Plan b! :)
I hate plan B, plan A was so nice!
