Adds an attachment to the email based on a file path.
Attachments over 100 MB are not supported.
Version 5 of MBS Plugin can encode file name for preserving non ASCII characters. Still for compatibility it is recommended to use simply ASCII names.
You can use Text.FileExtensionToMimeType to find the mime type for a file extension.
You can use AddAttachment several times to add several attachments.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.


Add attachment:

Set Variable [$r; Value:MBS("SendMail.AddAttachmentFile"; $EmailID; Attachment::Path; Attachment::Name; Attachment::Type)]

Recursive custom function to add a list of files:

MBSAttachment(EmailID, FilePathList, Flag_inline)

// e.g. $r=MBSattachment ( $EmailID ; MyTable::FilePathList; 1 ) ;

ValueCount (FilePathList ) > 0;
        §element =
            ValueCount (FilePathList ) ;
        §Line =
            GetValue( FilePathList; §element );
            MBS( "Path.LastPathComponent"; §line ) ;
            ""; /* file name from path automatically */
            ""; /* mime name from file name automatically */
                Flag_inline = 1;
                    §InlineID ;

    // call recursive for next file:
            "¶" & FilePathList;
            "¶" & §Line ;
