    Hello, i have a problem. I am using debian 11 with latest ispconfig, but i have a problem with send emails. Via roundcube, php mail etc works fine. I set up mail in thunderbird, i can recieve mails but when i try to sent it via thunderbird, get there error connection timeout, in error log i can see
    Mar 14 21:34:25 host dovecot: imap([email protected])<876970><kcLvmjPaNsVecJfC>: Connection closed (No commands sent) in=0 out=433 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=0 body_bytes=0
    Any idea please? Could be any error with ssl settings for smtp/imap?

    Wrong settings for outgoing e-mail server?

    Thank you. But i am not sure why i can sent emails via roundcube but is not possible via thinderbird etc. I will check outgoing settings.

    I solved it. Set port to 25, not 465

    The sending port for Thunderbird and other external mail clients is normally 587
