Hi,I have upgraded from zimbra 4.5.7 on centos 4.6 (32 bit) to other sever with centos 5.3(64 bit) and then upgraded zimbra 4.5.7 (64 bit) to 6.0.2 (64 bit) and now almost everything is working except outlook ( I have already solved lots of probelm by searching forums). In old server outlook was working with ssl configuration for smtp and pop3 but now outlook (with the same configuration) is receiveing mail but can't send mail and gives the following error.
"The server does not support a SSL connection. Account: 'mail.iut.ac.ir', Server: 'mail.iut.ac.ir', Protocol: SMTP, Server Response: '250 DSN', Port: 25, Secure(SSL): Yes, Server Error: 250, Error Number: 0x800CCC7D"
by the way, on linux workstation with evolution and kmail software every thing is fine.
So please help me how to fix zimbra 6.0.2 so that outlook can send mail with ssl (ofcourse outlook is sending mail without authentication now which I don't like to use it this way as our users have their old configuration with ssl).
