What should I do

Fix 550 5.7.24

Open the published v=spf1 record. Gmail says one or more entries in it are suspicious, and the bounce does not name which.

  • The SMTP error list and the sender guidelines are the two documents on this page. Neither row lists the terms.
  • A syntax error or a second v=spf1 record is a different result: permerror, not this bounce.
