Strange Mail Error

[Nick Furman]

Hi all,

        I'm having one customer complain about mail problems.  He uses
pine sometimes, and a mail client on another server (ATP Mail, it's a web
based mail program)

The error is this:

Jan 12 16:36:29 white popper[24578]: [EMAIL PROTECTED]: -ERR Unable
to process From lines (envelopes), change recognition modes.

Any ideas what that means or what i can do to fix it?

Please CC me on the reply.

Thanks!

Nick
