This is risky nowadays, since many spam filters reject mail 
coming from dialup or cable modem IP blocks.  If your users are 
all in one known IP block (such as for a corporate LAN/WAN) it 
may be safe.

While in the old days it was always safe to send mail through the 
host named "mail" on your local network, ISP's aren't quite as 
consistent anymore (e.g. my outgoing mail host is currently 
"smtp3", whereas "mail" is POP3 only) and you'll probably have 
to prompt the user for an SMTP server address.
