When I try to send a letter from Roundcube I get the following error:
|
1 |
Authentication failure: SMTP server does not support authentication (Code: )) |
This can happen if Postfix doesn’t allow authentication from a localhost where Roundcube resides or if authentication scheme is wrong.

I’m working with a Postfix/Dovecot/Roundcube setup, aiming for a virtual user mail system that can send mail through the internet. Everything seems to work well; Dovecote shows no problems, I can telnet into all of my ports; however, whenever I try to send mail through Roundcube I get the error:
|
1 |
SMTP Error (220): Authentication failed. |
