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.
