I've done similar configurations. Your problem isn't the mail client,
it's your MTA (mail transfer agent), most likely Exim, Postfix,
Qmail, Sendmail, or similar.
My own solutions have been:
- Email notification periodically to known accounts.
- Posting the current IP (and most recent update time) every ten
minutes to a known web site.
I currently use the latter.

For mail:
/sbin/ifconfig ppp0 | grep inet | cut -f 2 -d: | cut -f 1 -d' ' |
mailx -s "IP" [EMAIL PROTECTED]
Should post the message.
What you need to do is configure your local MTA to send this either
directly to the destination, or more likely, to your ISP's SMTP relay,
usualy referred to as a smarthost.
For the ftp version, I use a ~/.netrc file and set of scripts to post
the above IP information and a timestamp to a page. Scripts attached.

Irrelevant.
