The mailing list for listmasters using Sympa

[Steve Shipway <address@concealed>]

This isn't really a feature of Sympa, more of your mail gateway.

Our mail gateway (Ironport from Cisco) will allow a lot of control; we can 
set up a rule that will catch emails from an external source to mailing 
lists, and hold them in a quarantine for a configurable amount of time before 
releasing them back in to be re-scanned.  We don't do this, though, since the 
spam scanning is pretty decent and we use moderation instead on mailing lists 
where this is a problem.   We can also set up 'modlists' (like blacklists, 
but send to moderation q) for certain email senders or regexp matches.

Subject: [sympa-users] Implementing a delay on posts from unknown users?

I've been looking at SPAM that gets past my spam filters and onto lists, and
was wondering if anyone had looked into delaying messages that don't come from
"trusted" senders for some amount of time to be checked by spamassassin again
(after it has had time to get onto RBL lists, etc).
