Mal being sent to us is sometimes being bounced back

[bodminman]

Hi there,

 

we use Office 365 OWA (not that that should make too much difference) and we have had a couple of reports over the last few days of people who have said that when sending emails into the school, they're being bounced back.

 

I have sent a few test messages from my Yahoo account into the school and they appear, albeit a little slow.

 

One of the people who has had an issue has send me a copy of the error:

 

Sorry, we were unable to deliver your message to the following address.

 

<~~~~~@OUR_SCHOOL.co.uk>:

No MX or A records for OUR_SCHOOL.co.uk

 

I have checked and the MX record is setup correctly and the DNS stuff hasn't been changed in months.

 

Anyone got any ideas?

 

Thanks

Not specifically but we are waiting to migrate to Office 365 and have just been told that the LA have put the migration on hold due to delivery issues with the new update to Office 365 so this might be it?

Maybe!

 

About 5 minutes ago I sent another email from my Yahoo account and this one as yet hasn't arrived! There again it hasn't bounced back yet but I know that that could take time too.

Same issue & same error for senders. Been a problem here since last Sept/Oct - LA been looking into it but found no cause as yet.

Other message is "domain has no mail exchangers"

Senders email provider says: “There may be a syntactical problem at the (recipient) provider’s MX record, so that the sending system (e.g GMX) does not recognise the server name/address for incoming mail (which is part of the MX record)”

Good luck!
