Symptom: Senders are receiving bounces which state, "Message received has invalid format" when trying to send to an Axigen hosted mailing list.

Reason: Your mailing list is set to allow only messages with a certain type of content come through, but the person sending mail to the mailing list is sending using a type of content that is not allowed.

Remedy:

Log into your Axigen WebAdmin area.

Under Domains & Account on the left, click Mailing Lists.

Select the domain where the mailing list resides

Click Edit next to the mailing list you want to work with

Click the Subscription and Posting tab

Under the Message Posting area, adjust the slider accordingly

Click Save Configuration at the bottom of the screen
