If you’ve received a non-delivery error:

550 5.7.1 Our system has detected an unusual amount of unsolicited email originating from your address 

then it’s possible that the MailChannels system is blocking your email because they’ve noticed an unacceptably high volume of unsolicited email (spam) originating from your account.

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 password, 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 machine has not been compromised by spam-sending software (Virus/Trojans).

Once your account stops sending spam, the MailChannels system will notice the change and will begin to deliver your email once again.

If you are still receiving an error please contact us with the most recent error so we can investigate further:
