Restrict Sending From Address?

[Patrick Muldoon]

Looking at using the restrict_senders plugin, but from my digging that  
appears to work on IMAP username/domain they are logged in under.

Is there a plugin or anyway to restrict what a user puts in the from/
reply to fields. Trying to stem some of the crap that comes through  
the Webmail servers when $sillyUser falls for a phish or $badPerson  
guesses their password, and webmail is turned into 419/spam cannon for  
the 20-30 minutes till we find and kill it.

Going to be using restrict_senders to rate limit /block that way, but  
looking for even more way to tighten it down.

If no plugin exists I might look at coding one myself..

Thanks,
-Patrick

Just don't allow those fields to be edited.

config/conf.pl --> 4 --> 9

You don't need a plugin for that, but if disabling those fields is not
what you want, look at the Verify Reply-To plugin as a starting point.
