For lack of a better name, we are interested in a feature where one could get a notice out to all Dovecot users as quickly as possible, possibly without going through an MTA even. Given a message and a list of userids we could certainly do a mailing on the MDA server itself going through both Postfix and Dovecot LDA. However, we were wondering what other options we might have in Dovecot. For example, would it be possible to place the message into some file which Dovecot periodically checks for, and if the file exists, either present it to the user as a new message, or automatically deliver it at that time via Dovecot LDA? -- Steven F.

It's a really nice feature!
We have something like that with tpop3d (Chris Lightfoot's). tpop3d is
nolonger maintained but it's rock solid as a POP3 daemon. It gives this
feature via some perl hooks (plugin, I'd call it, for lack of the proper
word atm) and works very well.
It serves the "bulletin" without any reference to the MTA, and keeps a
DB of those users who have received/retrieved/pop-ed the bulletin(s)
so that they don't get them twice.
It's one feature I will surely miss if I migrated to dovecot 100%.

I have implented our quota warning the following way:
A script drops the warning directly into the user's Maildir INBOX using a
name, not created by any LDA.
Because using the "unique" name (starting with
"quotawarning") you can
delete any previous warning with ~MailDirINBOX/{cur,new}/quotawarning*.
New messages are picked up by the clients on a regular base :-)
