Modify mail server config and now having problem

[kajlaajay]

Hello Brothers/Sisters

Please help me out with this problem. I am new to linux and its commands i can only use a little vi editor. Sorry if this type of thread posted earlier but i need solution please.

Here is my problem - "SMTP Error (250): Authentication failed." in roundcube

i did some changes in my mail server like postfix and dovecot from some website steps to secure my emails but got only problems no solution. I modify many files in my centos 7 server to secure but nothing happen.

Few errors after using different website steps to use postfix and dovecot:-
1. SMTP Error (250): Authentication failed.
2. connection failed
3. nothing happen only processing in roundcube

Now i am not getting any mails and not able to send too.

To solve my problem i delete every line which i write for postfix and dovecot (i think i deleted but maybe few left which i dont remember or dont understand)

Please help because this is my production vps and i dont want to loose this server at all.

Other then mail server everything is working fine

Due to the fact that we do not know exactly what you changed, maybe this post can help you: https://talk.plesk.com/threads/email-err...ed.306524/

Just in case that doesn't help, you are not alone: Google: roundcube smtp error (250) authentication failed
a lot of people have gotten this issue.

Hi TGates

As you send these links i check and found that all those are on plesk as i told i dont know much about the linux operations and i have centos 7 with sentora. So please if you can help please do

I understand they are for Plesk, but the error is the same. If you do not have backups of your original configs, it makes things very difficult to fix. I can only suggest things for you to try. It's not a panel issue rather it's a mail server/roundcube problem. Maybe Me.B has some suggestions if he is not too busy.

Get back the default config files. Likely you broke it.

Check the git depot for the default configs and replace the correct strings.
