MailChannels Error: 550 5.7.1 Our system has detected that this message is likely unsolicited mail

Our partner MailChannels works very hard to fight spam. In order to ensure highly reliable message delivery for all of our customers, MailChannels sometimes reject messages.

A message might be blocked if it contains suspicious-looking or spammy text, or if the sending user has had a history of sending unsolicited messages.

What can I do?

If your account is sending spam, chances are it has been compromised in some way. Change your email and control panel passwords, and make sure you use a password that has

  1. At least 10 characters; and,
  2. A mixture of upper and lowercase letters, numbers, and symbols ($#%, etc.).

Once you have changed your password, run a virus scan to make sure your computer has not been compromised by spam-sending software (Virus/Trojan)

 

Once the situation is resolved the block should removed automatically after a short period of time.  If you are still receiving an error please contact us with the most recent error so we can investigate further:
