That's not what your regex has below. Let's analyze it. > [email protected]_asd_asd.example.com ---> [email protected] > But trying to go with this: > \N^(.*)@*_*.example.com(.*)$\N [email protected]$4 SF Wrapping the regex with \N is good. That means you don't have to do do all kinds of ugly escaping. What is messing you up is the @*_*. That literally means "zero or more @ signs followed by zero or more _ signs". What you meant was "@.*_.*\.example.com". You were thinking shell style or sendmail style wildcard instead of regex. Second, you said "with a domain part ending in example.com". But your regex searches for "example.com(.*). That means that example.com could match anywhere in the hostname. Finally, drop the $4 from the rewrite part. CentOS56[root@ivwm51 ~]# grep example.com /etc/exim/exim_TEST.conf \N^(.*)@.*_.*.example.com.*$\N [email protected] SF CentOS56[root@ivwm51 ~]# exim -C /etc/exim/exim_TEST.conf -brw [email protected]_asd_asd.example.com SMTP: [email protected] Regards....
