First, while it is not the issue you are asking about, your regexp is
probably more liberal than you want. I suggest something like


to preclude matching things like

   user at xyz.aaamynet.com


   user at host.mynetxcom

As far as your question is concerned, the sender address is retrieved
from the From: header using Python email library methods and
functions. If there is a bug there, we'd have to see an exact copy of
the split From: header to check that out.

Also, when your MUA folds the from header into multiple lines, it
should not be folding inside the email address. If by chance, it is,
then it is your MUA that is at fault.

In any case, I don't understand why this would affect only a regexp
match and not a string match. The address that is being checked is the
same in both cases.
