Hello
I got as far as being able to log on and receive mail. However, when I try to send mail, I get the error: (Authentication failure: Invalid response code received from server (Code: 454)).
I'm pretty sure it has to do with my SMTP settings, but I'm having trouble finding any solution, so if anyone could help, I would be very grateful.
Here is th content of my Roundcube error log:

You should look at your mail server log to see what that error code means.

Hi and thanks for helping out.

The mail server logs final lines  say (nothing about the error 454 in the entire /var/log/mail.log):

Jan  4 10:15:24 Blacknight postfix/smtpd[21084]: cannot load Certification Authority data, CAfile="/etc/postfix/ssl/cakey.pem": disabling TLS support
Jan  4 10:15:24 Blacknight postfix/smtpd[21084]: connect from localhost[127.0.0.1]
Jan  4 10:15:24 Blacknight postfix/smtpd[21084]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory
Jan  4 10:15:24 Blacknight postfix/smtpd[21084]: warning: localhost[127.0.0.1]: SASL LOGIN authentication failed: generic failure
Jan  4 10:15:24 Blacknight postfix/smtpd[21084]: disconnect from localhost[127.0.0.1] ehlo=1 auth=0/1 rset=1 quit=1 commands=3/4

I don't know why the CAfile cant be loaded, the path seems correct. Is it a permissions problem maybe?
Any help is much appreciated :)

**Update**
I can send mail using telnet, which I asume proves it's something wrong with my settings in Roundcube.

So the problem is with your mail server being unable to saslauthd, you should investigate further into why that is happening.
