Hello, running Professional 10.37. Once in a while, users will run into an issue where sending mail appears to go through and appears in their Sent box, but it doesn't actually sync to the recipient.
For example:
- I send an email to my co-worker: a@example.com > b@example.com
- My client, which in this case is Thunderbird, shows the message sent successfully and the message appears in my Sent box.
- b@example.com doesn't have my message. After multiple refreshes, the message still isn't there.
If I restart IMAP service, messages will sync immediately to the clients. I'm not sure why this is happening now. We were previously on 10.32 without this issue. I also recently put a different router in place in front of our mail server, could that have something to do with it?
