Currently we can route based off of MessageSourceAddress. But we are interested in routing messages to a folder based off of particular octets.

For example...(this doesn't work...just used to show what we would like to try to do on a conceptual basis).

if ($MessageSourceAddress == "192.*.*.100" ) { reroute("1"); }

We've tried escaping the wildcards, using 0s...I don't think that regex would work there...so what is the prescribed solution? Does anybody have something similar in place? Even just to get a host that ends in a specific octet would be helpful.

I don't think that regex would work there.

Why not?

Haven't tested but the following should work IMO:

if ($MessageSourceAddress =~ "^192\.\d+\.\d+\.100" ) { reroute("1"); }

    Thanks for your response. I had some time to work through it today, and we will see how it shakes out elsewhere. Currently getting a message that "Scheduled execution failed; procedure 'reopen' failed"...but this is so close. It was working...but when I went full scale something changed.

    It doesn't get filtered to the right directory on start, but the rotation part seems to get it (which is why I think I am getting that error).
