Regex SASL AuthenticationFailure Failed

[Grounz]

Hi,

Thanks for this great exporter.

We use it for get metrics of postfix server. We use postfix 3.4.13.

We have SASL authentication error in postfix server and it seems that the regex for capture SASL authentication failure doesn't works.

In fact, the regex rules is here https://github.com/kumina/postfix_exporter/blob/master/postfix_exporter.go#L299 this regex use ^warning and we have not this warning string in our smtp log.

Jun 08 14:39:03 myserver postfix/smtp[2107]: 837B04772D24: to=<[email protected]>, relay=mail.server.fr[IpAddress]:25, delay=1088, delays=1083/0.03/5.3/0, dsn=4.7.3, status=deferred (SASL authentication failed; server mail.server.fr[IpAddress]said: 535 5.7.3 Authentication unsuccessful)

And the metrics counter is empty:

postfix_smtpd_sasl_authentication_failures_total 0

have you an idea ?

Thanks you
