Well, i have opened a ticket and they said, that everything is correct. From TheBat to TheBat the Mails look fine. From TheBat to another Mailer (mostly Webmailer) the Mails look screwed up.
Ritlabs said, that it has to do with the Webmailer, which do not translate the HTML correct, which i don't believe, because the Webmailers are Gmail and Web.de (large german webmailer).
Also i recognized some other small problems with TheBats HTML translation, so i hope, that more people mention problems with this.

I have same problem with Orange webmail. I will try several e-mail clients for reading my html templates next week (incredimail, pegasus mail, thunderbird, outlook express and windows mail)
