Need help ingesting /var/log/mail.log.1

[rene_splunk]

I have a number of log-rotated files for mail.log in the /var/log folder on a unix system. The /var/log/mail.log file gets ingested just fine, so I know permissions aren't an issue. However, I'd like to also ingest the older data that was log-rotated, but for the purpose of ingesting, those files were untarred again, so I have mail.log.1 to mail.log.4

I have tried numerous stanzas and regexes in the whitelist, but none lead to the older data getting ingested. 

The one I currently have in place is:

[monitor:///var/log/]
index = postfix
sourcetype = postfix_syslog
whitelist = (mail\.log$|mail\.log\.\d+)

Thanks for any suggestions in advance.

Thanks Giuseppe,

I don't see any historical data in my index as yet, this is what's in the splunkd.log file

Hi @rene_splunk,

please try this:

[monitor:///var/log/mail.log*]
index = postfix
sourcetype = postfix_syslog

Ciao.
