Hi List!

Had a questions about imap vs. imaps.

I read the ssl article at http://wiki2.dovecot.org/SSL and from what I am reading, imaps is no longer needed as imap with initiate SSL/TLS on its own if STARTTLS is started and I have disable_plaintext_auth=yes and ssl=required settings.

I do have SSL up and working, and can connect using imap (143) to my server without issue, but was not able to connect using imaps (993) using Kmail as my client.

I Was getting a client error stating that the authentication failed using my password. However, there was nothing in the mail.err or mail.log file even when I enable debugging.

If I specify imaps as my only protocol, then dovecot fails to even start without any error loging at all.

As I stated, imap works just fine.

So, is imaps deprecated as mentioned in the article and imaps no longer needed?

I am running Dovecot 2.0.13 on an Ubuntu 11.10 64bit server. This server is simply an imap serer and not a MTA (No postfix or sendmail installed.)

Thanks! Joe

LOL, replying to my own e-mail...

I just discovered that the problem is most likely in my Kmail 2 client.

Tried to connect using the following:

openssl s_client -connect mymailserver.com:993

I was able to connect, log in, and get information about my mail folders.

Will try Thunderbird when I get home from work. Kmail 2 is still a WIP I guess.

That said, I am still reading that imap with starttls is the way to go, so might be a moot issue.

Thanks! Joe

Try this: (substitute your actual host for "remote.host")

openssl s_client -connect remote.host:143 -starttls imap

See if you get a connection. If so, then the server offers STARTTLS.

Hi, Jerry,

Thanks for the information.

Yes, I ran that command and got my cert and other information proving to me that TLS is working. I was also able to log in and get mailbox information.

Thanks again! Joe
