There are two additional Rules that could help preventing SPAM on Domino.

  1. Aking after empty Fields like from-Field

  2. ckecking of Systemfields like $Mailer or $MessageID.

Agree. Actually there are plenty more things that could be done simply by exposing MIME headers (or the full MIME source of messages) to permit processing by server mail rules:

e.g.

  • date stamps on received lines out of sequence or showing long delays in message routing

  • Received: from hostname.domain (where hostname.domain is victim’s own mail host, i.e. spammer is trying to make it look like your own host originated the spam - Domino records the HELO/EHLO argument in its received header)

  • excessive (or even any) HTML comments in MIME body

  • javascript in MIME body

  • and a whole lot more…

Started writing it up a while back but have been too busy to complete it.

Lotus guys, if you are listening, the spammers are winning again - we need a new weapon, easy for the masses to deploy, and server mail rules that can parse MIME would serve this purpose well.

Thanks for listening.

Subject: Mail Rules change to give access to all fields

The Mail Rules system can be “fixed” in the mail template with 3 simple changes to permit checking arbitrary fields. It would be nice to get this incorporated in the official template.

  1. Form “(RulesDlg)” > field “condition” > check “Allow values not in list”.

  2. Script library “Rules” > “FieldString” > “Select Case itmfield” > add code:

Case Else

FieldString = Strleft (itmfield & Chr (13), Chr (13))

vcondition = FieldString
  1. Script library “Rules” > “ConditionParser” > “Select Case strcondition” > add code:

Case Else

fieldstring = strcondition
