Have any of you noticed issued delivering email through MessageLabs to people who use MXLogic for spam/AV filtering? I've seen it more and more over the last month, to the point that I have to call 5-10 people a day to tell them to whitelist our domain in MXLogic. It isn't specific to a certain domain, just to Symantec/MessageLabs IPs. I've also seen this issue once or twice with domains hosted with Gmail, but those have cleared themselves up. -- Thomas York
