When a member bounces too much email, their status can be
changed to "held" that means that their email address has been
declared as "invalid" or "inoperational" and they no longer
receive list postings.
Lyris has the capability to send a
notification message to people on hold, to tell them about their status, and
give them the option of un-holding themselves. A member can unhold themselves
by sending email to "unhold@…" at your Lyris server.
This setting determines which
document is emailed to held members. The document is of type "about"
and must be created through the Lyris "documents" menu..
