Sending FAX with attachments using in RightFax

Hi,

We are in CRM 7. and sending Fax using  RightFax - Rightfax through SMTP/SAP Connect configured.

In case the outgoing Email in format html– attachment not sending through RightFax

(Mail document class is MHT)

I can see the mail with the attachment in SOST

In case the outgoing Email in format text– attachment sent correcty.

)Mail document class is RAW)

It’s probably related to mail document class,

But I didn’t  figure it out.

Thanks,

Liat
