I need a free SMTP server address (like smtp.softhome.net) which works good. This means:
1. No "relaying denied" messages.
2. No "free email..." advertisements at the end of the email.
3. No singups, "you must POP first" etc. messages.
Of course, it can be a non-free email provider which allows email relaying (I used aimnet.com for a while -- as an outsider, of course).
