Brian Nesbit asked,
I was trying to find some insight on how I can filter based on the
length of the From address.
Not enough to go on. Do you mean the envelope sender address in the
"From " pseudo-header, or do you mean the RFC2822 address in the From:
header? If the latter, are you including the formal name or do you want
it just stripped down to the email address?
Specifically I want to filter anything with
a From address greater than 55 characters in length ...
"Greater than fifty-five characters" is specific but "From address" is
extremely vague.
If you mean the envelope sender,
:0 flags
* ^From +\/[^ ]+
* 1^1 MATCH ?? .
* -55^0
action
If you mean the contents of the From: header, formal name and other
comments and all,
:0 flags
* ^From:.*\/[^ ].*
* 1^1 MATCH ?? .
* -55^0
action
If you want the From: contents stripped down to the email address,
that's more involved; if I were sure that was what you meant, I'd cover
that as well, but it's not worth it just on a guess.
