Problem with requiring client certificates for external connections
Folks,
I'm trying to configure my dovecot installation to require client
certificates for external/Internet connections, while still allowing my
local network to not need certificates.
This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've
tried to use the "remote" block to give different definitions for my
local network vs the defaults. While most options seem to

proxying, SSL, and client certificate
How do I configure dovecot-2.0.x to present a client SSL certificate when proxying?
If dovecot on server1.example.com has:
passdb {
driver = static
args = proxy=y host=server2.example.com nopassword=y ssl=yes
}
and dovecot on server2.example.com has:
ssl_verify_client_cert = yes
auth_ssl_require_client_cert = yes
then when a client connects to server1 and authenticates, a connection is

imap-login hangs after receiving revoked SSL certificate

My English is not very good, excuse me if I said something wrong.
I use dovecot-2.1.16 on Gentoo Linux amd64.
I need to setup dovecot (imap and pop3) for SSL and non-SSL connection
simultaneously. For SSL connections client must submit a valid SSL
certificate. Now SSL part of dovecot.conf looks like this:

IMAPS: Disable SSL connection without client certificate
I've been using Dovecot 2.1.8 on OpenBSD 5.2 i386 for about a month.
It works great. Dovecot serves IMAPS only, and I'm using Thunderbird
to access my mail.
I configured Dovecot to allow clients that present a valid certificate
when establishing SSL connection. I configure my Thunderbird for
SSL/TLS connection with normal password. It works fine.
However, with my config anybody

Disable Client Certificate Authentication for Unencrypted Connections?
I?m using dovecot to provide encrypted IMAP e-mail support for remote clients and it?s working great. However, I also need to set up a webmail front-end (Roundcube), which I?m hoping to have use unencrypted IMAP on port 143 (as only port 993 is available externally).
The problem I?m running into is that I want to require client certificate authentication on port 993, but dovecot is apparently

Postfix & Dovecot: Client certificate authentication
Hello,
I would like to set up an authentication using certificate with Dovecot: A user sends mail to Postfix and Dovecot authentication is valid only if certificate is trusted.
So, I enable the parameter auth_ssl_require_client_cert in dovecot configuration but it is not running. Here are the postfix logs:

]UG] Dovecot 2.2.9 SSL client cert verification fails: openssl verify: OK
Greetings all,
I have verified a bug that has long been attributed to lack of knowledge
on the part of the user.
Dovecot rejects StartSSL client certificates due to reject StartSSL root
CA when doing client verification even though the appropriately
constructed ca-bundle.pem has been created and applied vi ssl_ca =
</etc/dovecot/ca-bundle.pem.
openssl verify -CAfile ca-bundle.pem

Why does dovecot reject password when authorizing by a certificate?
You probably need to also enable
auth_debug=yes
auth_verbose=yes
also, are you sure you just don't have wrong password?

[SOLVED] Thunderbird client certification validation fails with same profile but changed IMAP server software (Re: It works for two SMTP servers and cyrus-imap, why not Dovecot?)
In hopes that searching may turn up the solution for others:
The reason client certificate validation was failing in Thunderbird when
it had previously succeeded with other servers (both IMAP and SMTP) is
precisely that: the client and profile where the same ones used to
connect to the server who's hostname hadn't changed, and email addresses
and usernames were the same, and Thunderbird

Different settings for SSL/non-SSL protocols
Good time of the day!
It is possible to setup dovecot with different requirements for SSL and
non-SSL protocols?
What would I like to do:
pop3/imap non-SSL = allowed plain text authentication.
pop3/imap with SSL = allowed plain text authentication with required
valid SSL certificates.
I need to allow access from any IP address for first group of users,
which have valid SSL certificates. And

SSL Client authentication with trustcenter-certificate
Dear reader,
we are using dovecot 2.2.7 and like it very much. Authentication is done
via a checkpassword program that does two things:
1) check wether the client has connected via SSL using a client certificate
2) check wether the client is using a one time password generator
Most of our users are using certificates that we have created ourself.
These certificates contain a
