Sendmail / remote mail?

Hi all,

I am somewhat knowledgeable about sendmail, and I use it, but am certainly no expert. Ok, I have a sendmail server, and it's name is "bob". Right now, all the mail clients are setup so that "bob" is the pop3 incoming and outgoing server.

That's fine. However, when away from the house (this is just a home network), then the only way I (or anyone else) can check e-mail is by putting the external IP address of the server as the incoming. This has got to be frought with security problems, yes?

What is a better way? Am I missing anything? Sorry for such a general question. I'm looking for a point in the right direction and would appreciate help.

Thanks, all.

Chris

Sendmail by default, when setup up for relaying other than the localhost, is an open relay. Keep an eye on your maillog for anyone using your MTA is a spam relay for themselves.

I setup a popB4smtp solution for Sendmail to keep this from happening at our company (and now researching SMTP_AUTH), but that might be overkill for a home mail server.
