We're trying to attach basic files to Newsletters. The email body is delivered successfully, but the attachment seems to have been dropped at some point. Going through network logs, the attachment never reached the SMTP server.
Compose a newsletter, attach a simple .txt file, clicked Send Newsletter
Next page shows review of newsletter to be sent, includes "Files" with bullet point "blank.txt (text/plain, 4 bytes)" , clicked Send
Next page shows "Newsletter successfully sent to 1 users." and the newsletter is received, but no attachment
Server 20012 R2
Mail Sender: SMTP
I suspect it's on the TikiWiki end that is dropping the attachment. Could it be something misconfigured on our php? Or, what module does the email attachment? Any guidance or insight is appreciated.
Uploading attachment to wiki pages, the rest of the site work just fine. Is the newsletter or email module using a different way to upload files?
