Website form submission notification email issues

[bodminman]

Good afternoon,

 

Our website changed hosts late last year and it's been flagged up to me that form submission notification emails are now no longer coming through to the schools @school.edu domain.

 

If we change the send to email address to @gmail or @Outlook they come through.

 

We have checked our Spamwall and there are no records of these notification emails even attempting to reach is and the host has said 'we have proved mail delivery works because the messages are going to the gmail and outlook account.

 

That may well be the case but we are not seeing the source IP, message subject or anything on any reports we run. We get info when reports are done based on the previous host IP.

 

We're stumped!

 

Has anyone got any ideas?

 

Cheers

Could it be that you have SPF and DMARC setup on your edu domain mail server, and the web server is not sending the message via your own mail server but a third party one and as such is failing the data checks so is getting dropped as spam?

That's what we check at first but the messages should still be leaving traces through Spamwall but it appears they're not even reaching Spamwall.

 

Sending messages to the same destination address via all other means is working.

When you sent a message to the other domains and it worked, did you check the message header to see what the sending address/server was.

If it was claiming to be coming from your school domain, but it is not an authorised senders then it could be getting dropped at any point before it hits your actual server.
