That's not when you need a port 587 server...

Port 587 is for when you take your laptop along to visit your grandparents,
and they have cablemodem from an ISP that blocks port 25. Now which do you do:
1) Whine at your grandparents about their choice of ISP?
2) Not send the mail you needed to send?
3) Make a long-distance (possibly international-rates) call to your ISP's dialup pool?
4) Send it back to your own ISP's 587 server and be happy?
(Hint - there's probably a good-sized niche market in offering business-class
mailhosting for people stuck behind port-25 blocks - they submit via 587/STARTTLS
and retrieve via POP/IMAP over SSL).
