Here's a wrapper for couriermlm that allows posting only from addresses that match a regular expression specified with POSTADDRESS in the mailing list's "options" file.

To use, save wherever you want, chmod +x and change your /path/to/mailing/list/.courier like this: | /path/to/couriermlm-wrapper msg /path/to/mailing/list

I'd like to see this feature (or equivalent) directly in couriermlm though, with options like POST=restricted and POSTADDRESS=<regexp>

Any chance? Would a patch that implements it be welcome?
