I am still struggeling to send a simple e-mail with a pdf-attachment to my VOIP-provider to fay that document. Needed is only the destination number in the subject-line and a password-code in the mail-textbody. The PDF has to be attached.
As all this works when doing it with my mail-programm by hand but nit if I use the Filemaker script step (sendung by SMTP) I am investigating what may get changed or added to a mail that might get mis-interpretated by the fax-server of the provider.
What I found out now is that a plain fax number (like "030123456789") gets changed to "?UTF-8?B?MDMwOTE2OTAzNjQ=?="
If I send the same mail by "Thunderbird" and look what the subject line looks like it is just the plan number. Therefore the problem must be here. How I can get a plain subject line?
