I’m trying to combine 2 regex strings to one
warning: non-SMTP command from .*\[([0-9a-f\.:]+)]:.+
and
NON-SMTP COMMAND from .*\[([0-9a-f\.:]+)]:.+
With a little modification I can get this to work in the online regex tester sites, but I need to add a /i flag for it to ignore case. How does one do that in the netfilter regex row lines. Adding /i at the end doesn’t make it effective.
