In order to get the Newsletter (Simplenews module) to send out emails correctly (in HTML format) I selected HTMLMailSYstem in the mail system settings. Having the DefaultMailSystem setting instead, does not work, in a sense that it only sends out plaintext newsletters, not html.
The status report however is giving me the following error:
Printer, email and PDF versions - Send by email Incompatible Mail System setting detected The send by email module requires the use of the DefaultMailSystem, please configure it in the Mail System Settings page.
Is it possible to have different mail system settings for different modules? Or is there another way for me to make this work?
