Hi everyone.

I'm just finished install Zimbra few days ago. It work without problem on web mail : sending, receiving mail
But when i tried to use Thunderbird yesterday, Thunderbird can't connect to mail SMTP.
For both POP3S and IMAPS, they are working fine. Thunderbird can fetch all mail to client.
But when i tried to send mail, Thunderbird just can't connect to server. It ask for password to authenticate but always fail. The same password worked for POP3S though.
I also try telnet 3 port and can connect to all 3 of them.

So is there any possible problem which make it like that ?
Which config should i choose for Thunderbird outgoing server ?
I tried with all 3 port 25, 465, 587, both STARTTLS and SSL/TLS.

Thank in advance
