Corrupted Email Messages

From approximately noon yesterday to 11:00AM this morning some specific kinds of messages with attachments over 512k may have been partially corrupted by some changes introduced into ours spam filtering systems enabling customers’ blacklists to be applied to all inbound email.  While these changes passed our testing and behaved as expected in our lab some clients appear to format messages in a way that causes a single carriage return in the message source to be lost.  This typically results in an email client not displaying the message body correctly while it still displays the attachments.  We are about to start an automated repair process but it is expected to take several hours to complete scanning and repairing any affected email in all customer’s email spools.  We’re sorry for any inconvenience this has caused.  –Kelsey and William

Update – As of 14:45, all corrupted messages have been repaired.
