[Mailman-Users] Blank emails due to convert_html_to_plaintext

Hi Mark,

Aaah you are right! I've just sent a text/html-only mail via Swiftmailer-script and the mail which arrives is empty aswell! I never would have thought about this as the hoster is pretty big and of course I assumed the conversion to be working. I'll contact them and hopefully they will be able to fix it soon.

Thanks a lot for your help!

Cheers,
Michael
