Re: file attachements

Nick,

I was thinking about your regex (I'm using something similar in a program I'm
writing), and on second thought it won't work.  The reason is that anything
enclosed in [ ] is implicitly "or'd."  The line:

>>/Content-Type: [^Text\/Plain]\;/i

tells PERL that within the square brackets to look for anything that is not T, nor
e, nor x, nor t, etc.  It doesn't read "Text" as sequential letters, but rather as
"or'd" letters.

You might try:

/Content-Type: text\/(?!plain)\;/i

This stands a better chance of working.  Some time ago I read through a small
portion of the PERL Majordomo script.  It had in it a line that deleted anything
from the list name that wasn't a letter, number, "_" or "-".  If the program does
this also in the configure commands then your line will be stripped to:

Content-Type textplain

It also might us the quotemeta() function.  If so the line will be neutered.

Hope this helps!

Glen
