OT: Email header question

Hi all, In light of the recent thread about email headers, somebody may be able to help with this one. I don't normally have any problems with the emails that I send out; however one particular person who I send mail to complains that anything I send to him appears in a much larger (unbearably so) font than mail that he receives from anyone else. Maybe someone can have a look at the header on this message and see if there's anything obviously missing (it looks fine to me) FYI, a reply from him showed the following info about his client: X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4522.1200 I suspect I send email to a good many people using the same client / version, so there's nothing odd about that. I'm using Evolution as a client on a linux box, with sendmail doing the address munging so that my reply address appears correctly, so that's a little atypical but not *that* odd. Anyone shed any light on what's going on? I would have said it was a problem with his client, if he'd been getting the same font problem elsewhere, but it seems like his version of Outlook doesn't like mail sent by Evolution for some reason... cheers Jules
