Keeping in mind most SMTP uses CRAM-MD5 or some equivalent these days with some portion of challenge/response from the server for authentication details... this of course happens automatically.

Some e-mail clients will go kicking and screaming on self-signed certificates, particularly in a virtualhosting environment where the common name needs to be a wildcard (*) for users to access the mail server under their own domains.

I love the paranoia around sniffing that many parties with an invested interest have encouraged.  In the end, your data transmits with some encryption on passwords from your PC, through a private network of your ISP who has tens if not hundreds of thousands of clients, then onto MCI/Verizon and other key players in core bandwidth into some datacenter.  Nobody of which has any care what your e-mail looks like.  Don't get me wrong, I'm all for encryption, but on services like e-mail it seems a bit excessive in favour of a challenge/response authentication.
Besides- these days odds are your PC will be infected and e-mail read on there rather than over the wire where it passes by your ISP aggregated with tons of other traffic at a few hundred Mbit/s.  Just my 2c.  Both are solutions to the problem, but 587 is more to avoid port 25 blocking by many ISPs as well as to run a SMTP service without ident/hostname lookups to ensure a speedier connection for mail senders, while keeping this on the ports that other mail servers send to.

why use port 587? the 'use secure connection' is right there, and if you're
doing any passing of authentication tokens across the wire, you should be
encrypting it.

that's just my two cents.
