Hi: I'm running dovecot on a Fedora 3 box and would like to be able to make a TLS connection to it with my Pegasus Mail program running on my Winblows machine. Does anybody know if it is possible? If it is I could really use some help configuring my dovecot. I have tried for several days but I really don't know what I'm doing and need a direction to start. Thanks, -- Knute

I asked a user today to make sure his incoming and outgoing email was using TLS. He told me it wasn't possible because my Dovecot / Postfix daemons were only listening on TCP 25 & 143 according to a port scan he did. He told me the only way I could enable encrypted secure sessions between the client & server is to enable port 993 (IMAPs). I told him that TLS is supported on my mail

I am running Thunderbird 2.0.0.14 on Windows XP. When I try to delete one of the folders I get a dialog with the following "The current command did not succeed. The mail server responded: Target mailbox doesn't allow inferior mailboxes." I am running dovecot version 1.0.13-6.fc8 under Fedora 8. The output of dovecot -n is below; [root at www knute]# dovecot -n # 1.0.13:

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

I switched from using Pegasus and POP3 to Thunderbird and IMAP for my email. Now I get a lot of "Corrupted index cache file" errors in my log. Dovecot is running under Fedora 8 and is version 1.0.13-6.fc8. The Thunderbird is version 2.0.0.14 running under Windows XP. My wife's Blackberry is also using IMAP and not reporting any errors. Any ideas what the problem is or how to

Hi to all. Is it possible to disable unsecure POP3 protocol at all in Dovecot 2.1? There was "protocols" option in 1.x version, and there was separate pop3 and pop3s modules. There is no "pop3s" in configuration files in 2.1.

Hello, I'm providing IMAP+Starttls on port 143 for users with legacy MUA. So I've to enable TLS1.0 up to TLS1.3 For IMAPS / port 993 I like to enable TLS1.2 and TLS1.3 only. Is this possible with dovecot-2.2.36 / how to setup this? Thanks for suggestions, Andreas

Hi all, Is there a way to enforce STARTTLS for all connections, regardless their authentication mechanism? disable_plaintext_auth only takes care of the auth conversation, but I would like to have all communication encrypted. As far as I can see, this would only be possible when using imaps and disabling imap. However, I would like to have the other way around; disabling imaps and using imap for

Hello, On a dovecot 2.0.14 proxy, I found that proxying managesieve works well when using 'starttls' option in pass_attrs, but does not work when using 'ssl' option. The backend server is also dovecot 2.0.14; when using the ssl option, it reports "no auth attempts" in the logs about managesieve-login, and meanwhile the MUA, Thunderbird with sieve plugin, reports

Hello list we encounter a weird SSL issue with one of our dovecot (2.2.24 on Centos6) which we can only explain if our assumtion is correct Symptoms are that imaps connections (on port 993) suddenly get veeeery slow. Up to 180s for one connection with openssl s_client The thing we do not understand is that in the same time imap connections with starttls are just 1s. We can see that entropy on the

Hi, I have a postfix+dovecot-2.2.13 system and have configured it to support IMAPS on 993 with SSL/TLS. I'm noticing with users using Thunderbird, the autodetect defaults to IMAPS on 143 with STARTTLS. Which is preferred? Which is more secure? Which is more common? Why would someone choose one over the other? Can I ask the same question about SMTP and submission? Why would one choose 587
