Hi,
My user has been experiencing multiple failures on sending email to mail servers that are being filtered by messagelabs (Symantec). I have ran query from multiple SPAM db host (mxtoolbox, Symantec). From the query, there is no list that points us as malicious nor error. Therefor, I've pasted the error that we were getting below for your attention/action:
