My server runs the latest FreeBSD (5.2.1-RELEASE-p3). I run the latest FreeBSD ports of Postfix and Courier-Imap. Both access user login information from either /etc/passwd (for local users in the smxy.org domain) or a MySQL (4.0.18) database (for all my Postfix "virtual_mailbox_domains" virtual users).
How users connect:
User logins are in the form of "user" for local smxy.org users, and "[EMAIL PROTECTED]" for all virtual users.
IMAP clients connect only to port 993, the secure imaps port.
When making an SMTP connection, on port 25, to send mail, the user's IMAP client must initiate a TLS connection, and then AUTH (Cyrus-SASL2, working behind the scenes). The first time the user tries to send via SMTP, in a given session, they are asked for their AUTH password. They are not asked again for the rest of the session.
Ok. As you can see, I believe in secure connections, so that 1) only AUTH'd users can relay through my server, and 2) all login details go over an encrypted link.
Rather thn provide an https:// version of all sites, local and virtual (which would require more IP addresses than I have), to run SquirrelMail over, I think I could set it up so that they could all get to SM by going to, say, "https://smxy.org/squirrelmail";, for instance, yes? That would satisfy my requirement that login details go over a secure link.
Once at that secure web page, they would be able to login in to their account, regardless of whatever domain it's in, yes, by just logging in as "user" or "[EMAIL PROTECTED]", yes?
Can SM cope with the server asking the user to AUTH, the first time they try to send mail, in a session? If so, how does it do this?
My apologies for the length of this, but I wanted to accurately describe my setup. Thank you for any advice you can offer me.
