| No. I would assume that the design is to allow anything that RFC 2822
| does. As far as I can tell, what you are seeing is a MMHostileAddress
| as defined in Mailman/Errors.py, and the characters checked for are in
| _badchars and _specials in Mailman/Utils.py. However, '.' isn't in
| there AFAICS, in a recently updated bzr checkout of 2.1.

I'm using version 2.1.10 (FreeBSD port) with Postfix 2.4.1 (FreeBSD
port). I just tried this again through the web interface (not as an
admin, but as someone attempting to subscribe) and I got the same
results. I used the address "jay.deiman at gmail.com" (without quotes) and
no name in the name field. Verbatim, I get this response:
You must supply a valid email address.
That is it. I've tested with other email addresses, not containing a
period, and they all work fine.
