by As you should know, there’s an important bug on TLS libs on every linux OS.
So upgrade is mandatory.
There’s also another little update in mariadb if you’re using it instead of mysql.
The problem is there, but not the indicator.
The problem in my case comes from the smtp server, I got the error:
535 5.7.8 Error: authentication failed: authentication failure
While tring to send an email (only sending, receiving works fine).
Looking in mail.log:
Mar 6 10:49:06 ciberterminal postfix/smtpd[29949]: warning: SASL authentication failure: Password verification failed Mar 6 10:49:06 ciberterminal postfix/smtpd[29949]: warning: localhost.localdomain[127.0.0.1]: SASL authentication failed: authentication failure
Auth failed from SASL? WTF!
So i began debuging it:
/usr/sbin/saslauthd -a pam -c -m /var/spool/postfix/saslauthd -r -n 1 -d -VVVVVVVVVV
But it only shows:
do_auth: auth failure: [user=dodger@ciberterminal.net] [service=smtp] [realm=ciberterminal.net] [mech=pam] [reason=PAM auth error]
Anything else.
Searching internet, I saw that post, I forgot to look for errors on auth.log!
Here it is:
