Michael & Tom,

Did you get to the bottom of this please?

We upgraded the BO on one of our servers last night and now have two 
separate customers that can't connect to POP3S giving the same error as 
above.

Unlike above this is is affecting POP3

We did identify a cert issue that the BO update overwrote and have fixed 
that again with...

cp /etc/admserv/certs/ca-certs /etc/pki/dovecot/certs/ca.pem
vi /etc/dovecot/conf.d/10-ssl.conf
ssl_ca = </etc/pki/dovecot/certs/ca.pem
service dovecot restart

But I can't for the life of me work out why it isn't working.

This is affecting an Outlook 2007 user on WinXP (I know) and an 
Entourage user on Mac.

I have manually checked the customers mail settings and they are fine. 
I can't get to the bottom of this.  The exact error we are getting is 
"your server does not support the connection encryption type you have 
specified" and error code 0x800CCC1A

Pls help

Thank you

Dan
