I spent quite a while trying to set up an alias in
config/postfix-regexp.cflike this:I wanted the client to recieve mail for a couple of users @customer.com and everything else to be sent to me so I can deal with maintenence stuff. The negative-lookahead regular expression seemed to be the solution but I couldn't get Postfix to understand it.
It turns out Postfix has 2 regular expression implementations denoted by the prefixes
regexp:andpcre:in config files. Perl-compatibe regular expressions (PCRE) seem to be the main implementation wherever I've used them before, however the Postfix config here uses the basic type by default.I am currently overriding by putting the following in
config/postfix-main.cfbut I think it would save people a lot of trouble ifpcre:was enabled by default for aliases.
