Resolved SMTP error 205

[Bénédicte]

Hey !

I have "SMTP Error (250): Authentication failed"
I followed the documentation to try to solve this problem but at point 6, my fields are not empty.

SMTP authentication fails on Plesk with SMTP Error (250): Authentication failed

Make sure that smtpd_tls_exclude_ciphers , smtpd_sasl_security_options , smtpd_tls_auth_only and tls_ssl_options are not defined in /etc/postfix/main.cf file (the output of the command below should be empty):

I have :
# grep -E "smtpd_tls_exclude_ciphers|smtpd_sasl_security_options|smtpd_tls_auth_only|tls_ssl_options" /etc/postfix/main.cf
smtpd_tls_exclude_ciphers = aNULL
smtpd_sasl_security_options = noplaintext
smtpd_tls_auth_only = yes
tls_ssl_options = NO_COMPRESSION

I just need to delete these lines and restart ?

Thanks for your reply !

Ok I delete these line and everything is OK

Yeah, you should delete the definition, not the entries. But first make a backup of the config. Than test the changes.

 

[Bénédicte]

I try to let the entries blank but it's doesn't work.
My mail loads indefinitely and stop if my config is :

smtpd_tls_exclude_ciphers =
smtpd_sasl_security_options =
smtpd_tls_auth_only =
tls_ssl_options =

Have you restarted postfix ?

 

[m3lezZ]

Otherwise try:

plesk repair mail -restore-configuration

or

/usr/local/psa/admin/sbin/mchk --with-spam

 

[Bénédicte]

Hello, yes, I have restart postfix.

I do the 2 command, but the first make me an error,
and the 2nd do nothing...

Are you sure I need to set EMPTY variables in my file?
I do not understand the interest...Can you explain ?

BUT when i do telnet now, i can send mail, but i don't have the line :
250-AUTH ***

 

[m3lezZ]

Could you please post the error-message?

Hi Bénédicte,
when you have this errors ? Are you using a php script, or using webmail ?
I think that your error can be resolve if you configure a good chipers method on the side of sending email.

Ok I do : plesk repair mail -restore-configuration and i restore main.cf (I have an errorto authentification)
And after I do /usr/local/psa/admin/sbin/mchk --with-spam
I restart postfix, and I think everything is OK !
Thanks
