procmailrc - substitute certain words to another.
 

i need substitute certain words in From: or To: or Body to another by .procmailrc
like..
From: bla <some@la.com>, joe <fuzzy@some.com>, other <some@some.com>
Just substitute "fuzzy@some.com" by "myfirend@some.com"

Basically you can feed it through a pipe with sed (or awk, but I am better with sed. The following recipe may not work for all of the cases you are interested in, but :

:0 fwh
* ^From.*some.*com
|sed s/fuzzy@some.com/myfirend@some.com/g

This will just pass the mail along for further operation, with myfirend@some.com (did you mean myfriend? :-) substituted for fuzzy@some.com.

If you want joe <fuzzy@some.com> to go to joe@some.com (just a thought), try the following:

:0 fwh
* ^From.*joe.*some.com
|sed -e s/\ \<fuzzy//g -e s/\>//g

You need the backslashes for spaces, redirects (<,>) and of course other special characters.

Good luck, Chris
