Mail Archiver X' user M. had a problem with Gmail sending out blank emails to some recipients. This happens if you have a AutoReply for the account in Gmail.
How to fix the AutoReply in Gmail?
- Click on the Wrench icon and then the See All Settings button.
- Scroll to the bottom and check the settings for "Out-of-Office AutoReply". If AutoReply on is selected and you don't have a date or a message then it's likely that Gmail is sending out blank emails.
- Remember to check the AutoReply settings for ALL devices and email clients.
What was really odd is that he didn't remember changing the setting. Gmail also didn't send out the AutoReply emails for all his incoming emails. Only for a couple where he got multiple emails from the same originator.
