Our company switched ISPs to Integra last week and since then every time we email anyone using bigfish.com, I believe this is Microsoft's
spam filter, we get the following rejection. I have emailed the delist address in the body of the email and they continue to insist we are not on their blocked list. Any help would be appreciated.
