Sentora Support Forums

Here is a pretty good troubleshooting guide: https://www.linode.com/docs/email/postfi...-and-mysql

I'm still checking into a couple of things.

Here is me checking the status of postfix:

Checked dovecot no errors.
Can't find any mail.log in /var/log/mail.log don't know if its located elsewhere or if its not logging at all.

It's telling you the issues, need to track them down (configs?)
Also, I found this to check dovecot:

stackoverflow.com Wrote:As a general tip, try running dovecot directly in the foreground:
dovecot -F
The reason is the foreground will often output loadup error messages directly to the console, which will often allow you to quickly track down errors that are not usually logged (such as config parsing errors).

Everything I check about the errors seem to point to a configuration error.

Also check this post i found: https://www.howtoforge.com/community/thr...king.2723/

Current Postfix Configs:

main.cf


master.cf

And the link you sent me was a problem with fatal: unsupported dictionary type: dbm

"fatal: need service transport:endpoint instead of "reject_unauth_destination" Im guessing is my problem?
dovecot -F didnt show anything in Terminal. Tried sending mail in Roundcube and its still Sending endlessly.

I know I'm using Ubuntu and TLS plus spam prevention methods, but maybe this will help:

So i got the emails working on my end but other people still can not use my smtp but can use a different smtp and work? This is an issue with two people. But i can. Pretty confused and the only output im getting is.


Which i looked up its a failed password. But the passwords are correct..
