Tetra WebBBS Configuration
Set $maillist_address to the address to be used for e-mails related to your BBS.
You should define this variable even if you don't enable the various e-mail notification functions, since the maillist address is also shown on some of the
BBS's pages to let people contact you if they have any problems.
The "@" character in the address must be "escaped" with a backslash if wrapped in double quotes (eg, "forum\@foo.com").
Using single quotes it must not be escaped (e.g. 'firstname.lastname@example.org').
