Hello, The patch # for ListenSMTP is NIFI-1899[1]. A PR[2] has been submitted and it is currently being reviewed. It should be adequately reliable and performant (if it's not it more than likely should be fixed). If you're able, it would be great to have another pair of eyes on it or even just help testing is always appreciated.
The prospective implementation of the ExtractEmailAttachments processor uses the Apache Commons - Mail MimeMessageParser to see if the message has any attachments. If it does it creates new FlowFiles from those attachments by streaming the bytes to the new FlowFile's content. I believe this method should allow for schema-less attachments.

I have a production system that reads email from a custom SMTP listener and places the SMTP payload into Kafka. A Storm topology reads messages from Kafka and parses the emails (Java code using JavaMail API) into useful info (subject, text, attachments, body, etc...). I'm looking at plugging NiFi into this to replace the custom SMTP listener. If you had a processor that could act as a reliable (we can't lose emails) and performant SMTP listener alternative we would use it. Your "email parser processor" is an interesting idea - but beware of the mess you'll find in the wild with email. In our case, we try to parse Exchange (full of non-standard wonders like "TNEF" attachments") as well as email from virtually anywhere (GMail, Yahoo, Joe's email client...). If you can crack that you'll be on to something. We have even more complexity in that we read "Microsoft Journals" which wrap the standard SMTP layout in a Microsoft layer (you'll see this at large Exchange shops doing this kind of thing for use cases like compliance). -- View this message in context: http://apache-nifi-developer-list.39713.n7.nabble.com/ListenSMTP-processor-tp10510p12827.html Sent from the Apache NiFi Developer List mailing list archive at Nabble.com.
