Sending mail from my iPhone

So I got an iPhone last weekend.  Yay for me.  I hope to do a blog post
about the experience this week.

I can get mail through IMAP, and I can send mail to myself, but I can't
send email to others from my phone.  I've made several attempts over the
years to get SMTP auth working and never succeeded.  Now I have more
incentive though because (1) I have a mobile mail client that is
actually usable, as compared to my Windows Mobile one, and (2) I'm going
to be going away without a computer for a while.

Here's what I get:
connect from mobile-166-137-137-090.mycingular.net[166.137.137.90]
setting up TLS connection from
mobile-166-137-137-090.mycingular.net[166.137.137.90]
mobile-166-137-137-090.mycingular.net[166.137.137.90]: TLS cipher list
"ALL:+RC4:@STRENGTH"
SSL_accept:before/accept initialization
SSL_accept:SSLv3 read client hello B
SSL_accept:SSLv3 write server hello A
SSL_accept:SSLv3 write certificate A

SSL_accept:SSLv3 flush data
SSL_accept:SSLv3 read client key exchange A
SSL_accept:SSLv3 read finished A
SSL_accept:SSLv3 write change cipher spec A
SSL_accept:SSLv3 write finished A
SSL_accept:SSLv3 flush data
Anonymous TLS connection established from
mobile-166-137-137-090.mycingular.net[166.137.137.90]: TLSv1 with cipher
AES128-SHA (128/128 bits)
NOQUEUE: reject: RCPT from
mobile-166-137-137-090.mycingular.net[166.137.137.90]: 554 5.7.1
<david-mNDKBlG2WHs at public.gmane.org>: Relay access denied; from=<david-8uUts6sDVDvs2Lz0fTdYFQ at public.gmane.org>
to=<david-mNDKBlG2WHs at public.gmane.org> proto=ESMTP helo=<[10.16.254.23]>

So I have a sneaking suspicion that the auth part is actually working
and there's another problem.  However, it does say "Anonymous TLS
connection" even though on the phone I have "Use SSL" turned on and I
specified a username and password.

One more observation is that I think SMTP+SSL is supposed to be running
on 465, and netstat says nothing is listening on that port.  I'm not
sure if running over SSL is a separate issue or not.

Thanks.
