Not always. When you use "roaming" dial-in you don't have local mail.
In this situation, you can usually read (pop) but not write (smtp).

Agreed.

Some more options:
1. Use SSH for connecting and tunnel the pop (110) and smpt (25) ports
to the mail server (thats how I work, from home and when I'm abroad).
The SSH can connect to any local (behind the firewall) machine.
2. You can allow re mailing from specific mail address by adding a line
like "From:[EMAIL PROTECTED] RELAY" to the access file.
(I use this form too, but I like it less, it can be abused).
Ehud.
