SSLv3 attack on pop3?
We turned off SSLv3 support on our pop/imap running dovecot on Oct 16th,
we did check that all users where using TLSv1 and there have been no
complaints (except one old windows-phone).
But at 13:00 UTC today, suddenly strange entries is seen in the logfile:
Error: SSL: Stacked error: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3
alert unexpected message: SSL alert number 10

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

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.

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

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,

SSL certificate problem (SSL alert number 42)
Hello,
After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported.
Mail server uses local (created for intranet) CA certificate as root.
I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels.

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

using signed certificates for TLS/SSL
Hi,
I have, in one customer, a web server running on a Verisign-signed
certificate SSL certificate. Everything works fine, IE and Firefox
connects on https without asking anything, which usually happens on
self-signed certificates. I'm trying to use that certificate on dovecot,
but clients (Thunderbird basically) keeps saying the certificate is not
valid.

SSL alert number 42
This is what I did. I obtained a certificate from this site:
https://www.sslforfree.com
They provided 3 files:
? certificate.crt
? private.key
which make perfect sense as replacement for the 2 files provided by the
distribution. I am guessing that I need somehow to append the 3rd file
(ca_bundle.crt) to the first one? In order to raise its credibility?
TIA

SSL error is it due to a self certified certificate?
Hi I have set up dovecot with a self signed SSL certificate, created with

Is this caused by my self certified certificates. Or is it

with thunderbird 10.0.12 i can't connect to port 993 and get errors in
the logs like

Evolution prompted to accept the cert; which I did.
Thunderbird used to prompt and allow acceptance; it no longer does...
well sorta does. See my other posting for a screenshot where it shows
"add server location https:// ...." HTTPS . no way to add from SMTP.
Have also tried typing smtp://host:25 and https://host:25

G Suite migration using dsync
Hello,
I am trying to migrate a domain from G Suite using dsync and am not
clear on how to configure so I am getting failures.
This is the configuration in dovecot.conf:

imapc_port = 993
imapc_password = 1234
imapc_ssl = imaps
imapc_ssl_verify = yes
imapc_features = gmail-migration
I also tried with imapc_ssl_verify commented.
For simplicity, both the username and
