Subject: Filter based on regular expression in from header
Date: Tue, 06 Dec 2016 15:18:15 -0600
I have lots of spam coming from .top domains. Can I fliter them in mfilter.rul with something like this if (isin("from","*.top$")) then call replace("Subject","*","WARNING Possible Spam - %1") redirect "email@example.com" end if it doesnt like the regular expression for the end of a line since it thinks its a variable. What are my options?
