To block spam e-mails before they get to my computer, I can filter at the ISP
- over half my spam is caught with word filters, but clever spammers use no
words or avoid or miss-spell the words I would filter on (e.g. "loan",
"Viagra").

It would be nice if image blocking worked!

When I block an e-mail address or domain I want it blocked - or moved to a
folder I can specify where it is not mixed up with the spam I have to sort
throught for non-spam.

The Outlook displayed "from" fields usually contains only a name, and not
the e-mail address (which is visible when you open the message). The full
email address is of limited use, as spammers change their email addresses
regularly. Respectable ISPs ban persistent spammers, so filtering on domain
is much more effective.

I am trying to write a VBA routine to compile a list of spammer's e-mail
addresses and domains from a folder of hundreds of spam e-mails, so I can
create a rule to divert e-mails to a folder I can specify.

VBA seems to lack anything to extract a specified field (e.g. from) from a
specified message in a specified folder.

If you use different rules and programs to divert e-mail, you have to use
different target folders to see the effectiveness of the different methods.
