I am getting a lot of spam with different names in the "From" field.
When
opening the e-mail, in the "From" field following the name are
brackets with
different numbers/letters but always the same domain name, then a
close
bracket. How do I get Outlook to block all spam from this domain name
in
brackets?
Add the domain to the blocked senders list (it's called different names
depending on the version of Outlook - and you never mentioned YOUR
version). Or define a rule that looks for the domain in the From
header. However, since it is spam, it is unlikely that is really the
domain from which the spam originated. Absolutely anything can be put
in the From header because it is completely unrelated to the commands
sent to the mail server (RCPT command for SMTP) regarding to where to
deliver the e-mail. A spammer might generate a username on-the-fly or
"borrow" them from the address books on a trojanized host and use any of
several well-known domains, like aol.com, ibm.com, microsoft.com, and so
on. I can stick a label on my shirt that says that I am you. Saying so
don't make it so but if all you're going to base my identity on is
whatever I have written on the sticker then I can pretend that I'm
anyone that I want to. Today I'm Bill Gates. Tomorrow I'm Catherine
Zeta Jones. Next day I'm you. There doesn't even have to be an e-mail
address in the From header.
Blocking on what the spammer purports is their e-mail address (or
domain) means you are naive enough to believe the spammer tells the
truth. It might work for awhile - until the spammer compiles his next
crop of crap to spew and then uses whatever usernames and domains he
wants at that time. Claiming an e-mail address is yours doesn't mean it
really is yours.
