SpamSieve Puts Good Emails Into Spam

SpamSieve keeps sending my wife’s emails to me into Spam. How can this be fixed. Repeatedly putting her on the white list does not seem to help

If the whitelist (or Contacts) doesn’t help, that usually means it wasn’t SpamSieve that put the message in Spam. For example, it could have been a server junk filter that did that. There is more information about this here.
