Fax over SMTP

I have following problem:

I made a special form to send faxes from the notes mail database.

In this form i specified for the Body field the option “Store contents as HTML and MIME” and in the form property the option “Store form in document” because i want to have the mask as cover.

If i use this form to send only text, everything works fine but if i try to send attachments, the fax will be sended without attachment (the attachment will be not printed) and at the end of the cover (mask) the fax reports following:

“see attached file: xxxx.doc”.

I already checked the location document (Mail tab - format for mails to send directly to the internet = “MIME-Format”)

If i use the normal Memo-Form everything works fine. What i do wrong ?

Issue on Lotus Notes Client Rel.6.5.5 and Lotus Domino Server 7.0.2

Any help would be very appreciated

Thank you !
