Why does my client report so many blocked emails?

  • Answered
I have one client who forwards me blocked emails all the time. It's not a matter of wrong email either. In the details of the email it reports: host mail3.statefarm.com [] SMTP error from remote mail server after RCPT TO:<••Redacted••>: 554 5.7.1 Service unavailable; Client host [] blocked using ASHB2VH2LBAJDLPVLNZ7XFLPCMMA4HP.r.mail-abuse.com; Mail from blocked using Trend Micro Email Reputation database. Please see I've gone through the process of requesting removal from the block list but I feel that this is a case of DejaVu. Any thoughts on how to prevent this?

I recommend ensuring both have followed our Overall Email Authentication guide. That should help prevent this from happening again.
