Everything Sean said is true, and should be taken as gospel.

The actual ereg for filtering a html-tag with attributes etc I do not

I can do more accurate filtering.
I'll assume you really mean this...
In say perl or php this would
definitely not be a problem and I take it that the eregs work the same?
The eregs work almost exactly the same. But that's not what you're
talking about. You're talking about a function named ereg_replace that
USES eregs. You use eregs in procmail. There are no functions.
Ok, so there is basically no ereg/replace function within the procmail
functionality then?
Since there are no functions, there are no ereg/replace functions.
But your suggested solution is certainly an option!
Could anyone give just a brief example on how this would be done I'm
sure I could work out the rest.
As long as you don't exceed buffers (configuration of which will be left
as an exercise for the reader), you could conceivably do something like:
MSGBODY=`sed 's/<[^>]*>//g'`
:0
* MSGBODY ?? debt.free
* MSGBODY ?? extra.money
* MSGBODY ?? learn.more
* MSGBODY ?? cash
* MSGBODY ?? refund
action
or
:0
* MSGBODY ?? penile
* MSGBODY ?? pills
* MSGBODY ?? confidential
action
Personally, I'd be happier looking for "<[^ >@:/-][^ >@:-]{10,}>":
Z="[^ >@:-]"
:0
* -10^0
* 1^1 $ B ?? ()<[^ >@:/-]${Z}${Z}${Z}${Z}${Z}${Z}${Z}${Z}${Z}${Z}+>
action
This still gets lots of positives though, notably inside BASE64-encoded
attachments, headers, C source code and configuration examples that put
<your_option_here>.
If you develop it into something useful, please let the list know.
