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
