TLS for IMAP authentication or smtpd sender authentication?

Postby laramie » Thu Apr 01, 2004 4:18 pm

Is it possible to enable strong encryption options for IMAP authentication and for smtpd sender authentication?

For IMAP, I'm interested primarily in running an SSL-enabled IMAP daemon on port 993 or advertising STARTTLS on port 143.
For smtpd sender authentication, I'm interested in advertising STARTTLS on connections to port 25.

If not currently available, will these features be added to a future version?

We don't offer TLS built in to the IMAP server or SMTP Relay. Our recommendation in these situations is to use stunnel to forward from the encrypted ports (993 and 465) to the plain text ports (143 and 25).

The following entries can be added to your stunnel.conf file:

[imaps]
accept = 993
connect = 143

[ssmtp]
accept = 465
connect = 25

It's not currently in our plans to add strong encryption but I can certainly add it to our list of enhancements for future releases. Please not that this is not a commitment to fix and it will be scheduled accordingly against any other enhancements.

Best regards
