Hi, Couple of questions about sendmail. I enabled SMTP AUTH (using the Cyrus SASL and PLAIN and LOGIN methods) on a stock Red Hat 7.1 Sendmail 8.11. The LOGIN works fine for local users relaying mail through the company server, except for a couple of issues.
First off, I also need to enable STARTTLS in order not to have passwords transmitted in clear-text over the wire. However, STARTTLS appears to require a certificate on the client side, and self-signed client side certificates don't seem to work, especially with Outlook clients. Nor with Netscape Messenger either, for that matter. Any tips on getting STARTTLS to work with self-signed certificates? I've read most of the standard docs which Google threw up, with no joy forthcoming. Secondly, is there any way to tell sendmail that if, e.g user ``raju'' logs in using SMTP AUTH then it should only relay messages which come from that client AND which have ``[EMAIL PROTECTED]'' as the sender address? In other words, even with SMTP AUTH enabled the sender can choose any envelope sender and make the message appear to be from another person. PGP, GPG and S/MIME aren't options, since most of the mail recipients aren't clued in enough to be able to figure out what a signature is or distinguish a good signature from a bad one, so we need to be able to configure Sendmail to check and reject messages with forged envelopes.
