Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Recently thunderbird and Dovecot IMAPS cannot agree on SSL however
Evolution, on the exact same system, is working fine with the same
accounts. Tried recreating the Dovecot cert and also the thunderbird
accounts from scratch. The OpenSSL raw client works fine as well.
Would someone also confirm the openssl commands to create a selfsigned
cert for dovecot imaps. They cert created does work

SSL cert problem
Hi,
I'm running a new dovecot 2.0.9 under Centos 6.4. I'm having an issue with
SSL certificate not being accepted by the email client.
I have my own CA and I have generated certificates for web usage without a
problem.
For imaps and pop3s what I did was generate a certificate for the hostname
of my dovecot server and then cat that cert with the intermediate and root
CA certificates. No

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Hello,
This is a selfsigned cert. Both of the below methods were used.
May I ask for 1. pointer to info setting up "intermediate certs" and
where the certfile goes?
The objective is to generate a self-signed cert and use it for just
internal use with IMAPS dovecot.
Separately, what are your thoughts as to why evolution works and
thunderbird does not?
Thank you,

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
I would expect the public cert to be imported as a "server" not an "auth"
The attached image shows that TBird wants an httpS url for a webserver,
for the source.
Ages ago, I think it prompted for "do you want to trust this new cert"
and YES added it (assuming that is the public key) to the server list.?
A bit confused by this.

using ecc-certificates (ellyptic curve) will not establish connection
hi
I want to use ECC(ellyptic curve cryptography) for SSL-connections but somehow dovecot doesn't like my ECC-certificates :(
I tried to test using following scenario:
machine:
debian 6 (x64)
dovecot 2.0.15-0~auto+21 ((f6a2c0e8bc03) from http://xi.rename-it.nl/debian
openssl 1.0.0e-2 from testing (as the default 0.9.8o-4squeeze3 needs also the parameter -cipher ECCdraft for testing)

SSL stops working after server upgrade
Hello, after an upgrade of the dovecot server, I can not use SSL
connections. Can you help me solving the issue? When googling for the
error, there is an opinion that the client is broken (in my case
Thunderbird, 3.1.3), but I rather see the issue in the server, because I
was upgrading my gentoo box by hand, and the secure imap stopped to work
after that. Is there a more verbose SSL logging

My dovecot works fine against Active Directory 2003, but not against AD2008
Fran and/or Matthias,
Could you publish your doveconf -n? I can't get dovecot to authenticate with my
AD. Maybe you have a solution I could try.
What mail client(s) are you using? I assume by "AD 2003/8" You mean SBS2003/8
and are therefore using Outlook?

Misleading SSL/TLS Log Messages
Hi all,
I think I've found a small bug in how Dovecot logs SSL/TLS info. Basically,
if I connect to the server using TLS, the logs have a lot of entries saying
I used SSLv3 (which is not allowed). Here's my system info:
OSX Yosemite (x86_64, HFS+)
Dovecot 2.2.15 (via Homebrew)
OpenSSL 0.9.8zd
The configuration (see below) disallows SSLv3, and if I try and connect
with OpenSSL to test

SSL with startssl.com certificates
I'm using Dovecot 2.2.5. I'm setting up and new IMAPS server for
personal use (i.e. only me).
I have success with self-signed certificates but not with others (e.g.
StartSSL.com)
With StartSSL certs:
I've been able to connect and test commands via: openssl s_client
-connect imaps.unixathome.org:993
Can you configure your iPhone or Macbook to access the above?

Dovecot IMAP is broken after upgrade from 2.1.2 to 2.1.3
Hello,
I just upgraded my servers from Dovecot 2.1.2 to Dovecot 2.1.3-0~auto+5

Debian binaries from "http://xi.rename-it.nl/debian/
stable-auto/dovecot-2.1 main".
The config was not touched but now IMAP connections are not possible
anymore (LMTP works fine).
When I try to connect to a mailbox, the connect fails.

my dovecot installation has been working fine against AD till we upgrade
