sebres e605415f61 simplify fields-group a bit (everything up to 4 chars long but H), so it'll be faster (no multiple branches) as well as would theoretically accept future enhancements of logged fields. 2024-03-22 16:47:54 +01:00
sebres c22a83933b let's use `<ADDR>` instead `<HOST>` - only IPs expected, since host-name bypassed before it (directly after H=) 2024-03-22 16:35:46 +01:00
Vladimir Varlamov df94ec4c52 filter.d/exim.conf: rewrite host line regex for all varied exim's log_selector states 
Depending on Exim's log_selector settings, log lines may contain additional information about the connection. And also the line itself with the address of the remote host can vary greatly. But fortunately, all states can be found in the Exim code itself and taken into account. Makes it easier to add new regexps.
Closes #3263
