I run a vBulletin 4.2.5 based Forum and I have been using a YahooGroup for many years to send out new forum messages to members via eMail.?
This is done by adding the email address to the settings for each forum.

I have been doing this for many years to my Yahoo Group and this service is popular with our members. As YahooGroups is closing, I decided to setup a similar group here and am currently testing it. Strangely, the emails are not arriving on groups.io from the forum. I have checked that the forum is correctly sending out the emails (as it has done for years) and the forum uses the Amazon SES service with my correct email address as registered with groups.io?
If I send emails using Outlook from my PC, those emails arrive at my groups.io account normally. The sending address is the same in both cases.?I have to get this working reliably before I can transfer my group over here.?Here is the header info of a test email I sent to myself. I have changed the domain names in this example, but otherwise this is what would be arriving at groups.io - what is not working here that causes these email to not appear. I have not received a bounced email, either.
