_What_ has happened? You haven't told anything at all about what has
happened. Has Google's sendmail server rejected your emails? If so,
what error message (or reason)?

You suspect that Google's MTAs take a look at the X-Mailer header and
reject messages when discovering "Claws Mail" in there. That's a bold claim
and highly dubious. Has this been mentioned and discussed anywhere before?

I'm not aware of any Claws Mail users having problems sending emails to
Google Mail accounts. Give some more details, please.
