Filter syntax options in serverclass.conf

Peter — Mon, 29 Mar 2010 19:50:00 GMT

Is it possible to use regular expressions for the whitelist/blacklist filters in serverclass.conf? For example:

whitelist.0=mail[0-9]+.*

It is not possible currently (version 4.0). Only * as a wildcard for any character can be used.

I see that PCRE expressions have been added as of 4.1, but the mappings confuse me. My current serverclass.conf has name8., which mean to match name8.blah and name8.bleh. It would be easier for me to match name[0-9]+.., but the docs seem to indicate that '.' is converted to '.' and '' is converted to '.' Can you add clarity to this?

If regex in these whitelists are anything like the regexp in stanza names, there was a bug in the docs. . means dot, * means anything but slash (meaning filenames only) and ... (three dots) means anything, your usual regex .*
