Kindly confirm and provide the proper solution.

Weird Dovecot 1.1.6 + pop3s certificate issues
Hello everyone,
I've been asked by a colleague to have a look at some extremely weird
dovecot SSL issue they are seeing on one of the student mailservers.
They are running dovecot 1.1.6 (yes, I know, a bit old ...) on SLES 10.2
x86_64 with imap(+starttls), imaps, pop3(+starttls) and pop3s enabled.
Every couple of weeks the pop3s and pop3+starttls part bail out out.
Clients can't connect,

Hello,
i have a user who is able to do pop3 on port 110 without problems and without limits. There are ~10 real users using same public IP.
When switching to port 995 to use pop3s he is limited at connection count. Some people can reach pop3s-server successful, some getting a timeout.
I cant find any errors or limits within my config or in my log, there are no differences between using plain text

Dear libvirt team,
we a currently in a pci-dss certification process and our security

test49 Authenticate PLAIN disabled stops pop3s
Unlike test47, test49 refuses to authenticate pop3s
if disable_plaintext_auth = yes
Checked the crypto with: snort -vde tcp port 995
The connection is being made with ssl so it looks like
the plaintext auth preventer is broken.

I've spent days scouring the Internet and trying various solutions on a

learned in hopes of saving other people a lot of time.? The dedicated
Dovecot hands will know all of the following already.? This is for those
of us that have to cover a lot of bases.

Panic in version 1.1.6
Hello,
We have seen a few of these panics in 1.1.6. It seems to happen when pine

but I'm not positive this is always the case:

changing cipher for imap clients
When my client connects, I see this in my log:
dovecot: imap-login: TLSv1 with cipher ECDHE-RSA-AES128-SHA (128/128
bits)
Whereas, when client connects to my postfix server, I see:
Anonymous TLS connection established from * TLSv1 with cipher
ECDHE-RSA-AES256-SHA (256/256 bits)
how can I tell dovecot to use AES256, instead of AES128 ?
is this set by ssl_cipher_list ? Here are my current
