I am using Office365 and facing an issue in sending email to my client. Apparently my client has blocked certain IP addresses which their organisation found from external sites like MXToolBox.com.
Unfortunately the IP I am sending out was blocked by them as it was identified as spam. Can Microsoft please assist on this?
This url was marked as blacklist by MXToolbox.com
mail210-co1-R.bigfish.comHere's the trace.
