This is regarding email for domains that we host and where we have configuration such as Aliases to forward incoming email on to a third party email address. eg: if you have a domain with us and have email forwarded somewhere external such as a Gmail account. Customers who collect email from our servers by POP3 and IMAP were unaffected, as were email that customers send through our smtp.aa.net.uk relay.
We had a problem between 2PM on 25th August and 2:15AM 26th August where incoming email for customer domains that are configured to forward email on to a 3rd party email address would have been failing and subsequently lost.
This was due to a configuration change we made in how we relay email on to third party addresses. The change was applied and tested to be working ok. However, a few hours after this change our email systems had automatically blocked ourselves from sending email. The problem was fixed at 2:15AM when we became aware.
We do apologise for this. Unfortunately it's not possible to recover the lost email. We will have logs of messages that were lost, if customers need this information then please do email in to support@aa.net.uk
