I need a solution
My boss got this symantec error this morning when trying to send an email: "Your email message was unable to be sent because your mail server rejected the sender: 421.4.7.0.z.nysa.us Error: too many errors. This only affected him and it was fixed by him renewing his kerberos ticket, which has nothing to do with symantec. I was wondering why it was symantec that was giving him this error. Whether it's relevant or not I am not sure but we switched symantec servers this morning but as I said he was the only one affected.
