Hello Xavier,
did you have any success disabling SSLv3? I would like to disable any
old ciphers and turn on Forward Secrecy. Do you have experience with
this and perdition?
Thank you,
Alex

Hi,
AFAIK, this enables STARTTLS in the port instead of starting a
purely encrypted connection.
nc -vv imapproxy01i 993
Connection to imapproxy01i 993 port [tcp/imaps] succeeded!
* OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES
* MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE
* LOGIN-REFERRALS STARTTLS LOGINDISABLED] perdition ready on
* imapproxy01i 00028de7
I haven't tested but I think this may not change the list of
accepted cyphers. After reading the manual and some messages in
the list, it seems that all references to TLS in the
configuration are aiming at STARTTLS and the only way to change
the valid ciphers is with *ssl_listen_ciphers* and
*ssl_outgoing_ciphers*. Am I mistaken?
Regards,
Xavier Garcia

I have got perdition 2.1 setup and configured to do mysql lookups.
IF a user is not found...
.... status="failed: Could not determine server"
I'd like to have a default/fallback server to use.
Is that possible... I was thinking that maybe a mapping from: popmap.re
might work.. but it doesn't seem like it looks at BOTH the mysql entry
and the popmap.re entry.
I am wanting to be able to ONLY list in the mysql table certain users
that are on 1 imap server and have all other request go to our main imap
server.
Thanks - jack
