We are aware of outbound SMTP delivery issues on server01.r02.easyhttp.co.uk This has been caused by a compromised user account on this server that has been used to send out a large volume of SPAM. The account has been terminated and is being dealt with however, it has resulted in temporary delivery restrictions from some remote hosts such as Yahoo, Hotmail and AOL.
We are monitoring the situation. Any failed emails depending on the remote host will be queued for re-delivery. If delivery restrictions remain for over 24 hours then we will look to divert outbound email flow via another internal SMTP array on the sort term.
We apologize for any inconvenience caused.
UPDATE01 – 16:00
SMTP traffic from server01.r02.easyhttp.co.uk is being relayed via another smart host as this is affecting internal support sites.
