SMTP Error (535): Authentication failed.
 02-13-2015, 10:06 PM
I get this error when i try sending mail from Roundcube. I have port 25 open and SMTP services enabled on my VPS.

I have configured and installed postfix, sendmail and csf.

I was asked to locate main.inc.php config file of roundcube package and make certain changes but I cant seem to locate this.

Anyone able to help?

Thanks

You mean you messed up sentora setup that way? Explain what you did EXACTLY step by step as this is what messed up your config.

Why installing sendmail? We have postfix there! And why installing postfix? It's already installed and setup by default by installer?

Provide more informations and details.

Hi..on default server installation I noticed that smtp port 25 was closed. it only became open when I installed csf.

Are u suggesting I remove the postfix/sendmail installation ?

SMTP port 25 is open by default! You must have a custom setting here...

Use the standard recommended config: MINIMAL CENTOS install and don't add sendmail or postfix in any way.

If it's on non production server i think you should reinstall Sentora again from minimal server and test all this !

installing sendmail just messed up the Postfix dovecot config of Sentora !

You must be WRONG as postfix is installed by sentora. and you SHOULD NOT install SENDMAIL! all the required stack is installed by sentora it self. I'm quite sure you have some custom install or failed install. Check again logs/services running.

You didn't even expose the OS you use and kind of setup? VPS? Vmware?
