Re: Regular Expression Syntax Error: Invalid regex in realm

Therefore, in order to process "example.com" and all sub-domains of it which means "*.example.com"

No. *.example.com means just subdomains of example.com. It doesn't include example.com.

you should write rules seperately for @example.com and @*.example.com.

Yes. example.com as any other realm, subdomains as regex. Ivan Kalik Kalik Informatika ISP
