Hello All,

We found a bug in Python's email parsing routines. The bug seems to be
present in older versions of Python and causes ASK to incorrectly parse some
email addresses. All versions of ASK running those versions of Python are
affected.

The bug affects the parsing of emails with an unquoted user name and a dot
character anywhere inside the user name part. Example of an affected addres=
s:

John Q. Doe <[email protected]>

Emails containing quoted user names or no user name at all are not affected,
such as:

"John Q. Doe" <[email protected]> or
[email protected] or
John Q Doe <[email protected]>

If your version of Python has this bug, ASK will not be able to correctly
parse some emails causing the confirmation message to be sent to an invalid
address.

To determine if your system is affected, please execute the Python program
attached. If possible, send the results to [email protected] or to
the ASK-users mailing list. We'll update the recommended version in the
documentation to reflect the lowest version of Python that does not contain
this bug.

Many thanks to Nils Weisensee for relentlessly tracking this bug.

Regards,
Paga
