I've got the mail receiving but I can't send mail. checking /var/log/mail.log doesn't show any errors, they are just client side. All the ports are forwarded (dedicated server with WAN ip, with ports forwarded via UFW). 110 ALLOW Anywhere 143 ALLOW Anywhere 25 ALLOW Anywhere 465 ALLOW Anywhere 585 ALLOW Anywhere 587 ALLOW Anywhere 993 ALLOW Anywhere 995 ALLOW Anywhere main.cf: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

Are you authenticating before you try to send mail? What does the log show you at the point you try to send an email?
/var/log/mail.log shows nothing at that point. I've tried changing all the methods that thunderbird has for user auth to the smtp server but no luck with any of them. I pulled the clamav/spamassasin mix out to simplify and try to weed out extra errors.
Is your server located somewhere else? (as in a datacenter for example) In that case, it could be that your ISP doesn't allow you to send emails via other mail servers then theirs .. you could try submission (port 587) uncomment those lines in master.cf and restart postfix. Then try to send mail via port 587
It is located in an OVH datacenter. I will try the submission setup. *edit* That appears to work. Thank you so much. Strange they are blocking port 25. Changing the regular smtp port to any other port worked as well.
