: Hi,
:       The problem is that something is added or removed to the mail
: after it is signed. By "mail" I mean the full mail (with headers).
: Some headers are not contained in the signature (like the
: "delivered to" headers) because it is normal to be added after the
: signature but others (like subject or a footnote in message body
: advertising a service (common in free email services)) should not
: be changed after the signature. 
: 
: Common email clients SHOULD NOT create such problems. Homemade on
: the other hand...

Christos,

        I use O2k, and I'm a paying customer of both Lycos, and Yahoo, so
they're not tacking on any footers for ads or the like.  As you'll
see in another post on this topic I've adjusted all my settings to
wrap at 70.  Let's see IF that takes care of it or not. . .
