[Mailman-Users] Are the "regexps" used in Mailman really RegularExpressions?

[Jeff Groves]

Thanks for the quick response, Mark.  The web site you provided below is VERY helpful to me.

I'm still experimenting with another issue in 2.1.5, so my hypothesis may be wrong, but it is 
kind of looking like the "acceptable aliases" part of the Privacy options in "Recipient 
Filters" is case sensitive.  So, if I enter MailingList at foo.org as the address of the list 
and I only have mailinglist at foo.org, then Mailman throws a "no implicit address" error.

Can anyone refute or confirm this hypothesis?
