RETR failed to Feed Message for message 56
Question asked by ANXO - 8/25/2021 at 7:35 PM
Last week ,I upgraded the server from 7242 to 7901.
Today I received the  message from user.
The message is as follows:
"RETR failed to FeedMessage for message 56 (UID: 20166) ERR: The group file D:\SmarterMail\Domains\(Domains)\Users\(user)\Mail\Inbox\2021_8_11.grp is corrupt or a message could not be found in the header.."

Does anyone have the same problem??
How can I Fix it?

Good morning! I'm sorry to hear you're having trouble with this. This error indicates the GRP file referenced (mail data) is corrupt, and will need to be restored from a backup. This should be done from a known good backup copy with the SmarterMail system service stopped. When finished, have the user attempt retrieval again and this should clear right up. Please don't hesitate to submit a ticket with us if you need any help.
