Emails with attachments to Mailing Lists not delivered (16.3.6726)
Problem reported by Matt Lyons - June 2 at 8:59 AM
Resolved
Emails with attachments to Mailing Lists are not delivered. Emails without attachments are being delivered.
I'm running SmarterMail Enterprise Edition - Version: 16.3.6726
 
The non attachment emails have this in the delivery log:
 
[2018.06.02] 15:19:52 [64142] Delivery started for testlist-cec519d2fda149f7b859b22b96228c8d@somedomain.com (via admin@somedomain.com) at 3:19:52 PM
 
The emails with attachments have these in the logs:
 
[2018.06.02] 15:09:42 [64125] Delivery started for  at 3:09:42 PM
[2018.06.02] 15:09:42 [64125] Spool message was missing Return-Path; Also missing FROM header

I've tried changing the List To Address and List From Address but that didn't help. I created a new list and it still doesn't send attachments. I can't find any other settings I can change.
 
Anyone else experience this?
 
Any suggestions for me?
 
Thanks,
~ Matt

Hi, Matt
 
I just tested this on the same build and my emails with attachments sent to my list just fine. I realize this is a basic question, but is the file type you're attempting to send as an attachment an allowed file type?

Hi Derek,

Thanks for checking this with your build. The attachments are .jpg's.

I have an update to this problem. The emails with attachments to the mailing list show up on the subscriber as a bounce. After three bounces the subscriber is automatically removed. So now all the subscribers are gone.

In case this ever happens to anyone else, I finally found my problem. The Max Message Size was set to 30. I changed it to 30,000 and now the emails with attachments are getting though. I don't know how this got changed. I suspect the domain admin changed this not realizing what KB was for. What a weird problem to have.
