Error: ===Failed to move message 00000XXXXX with reason 183

[Igor__K]

Quite a lot of such error messages in SMTP log file
What is the actual reason and how to get rid of it?

[adrien]

error 183 is "Cannot create a file when that file already exists."

that means WinGate is trying to move a file, and afile already exists with that same name in the target folder. This most likely means the file has been previously moved already.

Message files are received into Mail\Spool\Incoming, then moved into Mail\Spool\PostIn when they have been scanned (e.g. by Kaspersky AV for WinGate if you have it installed). then they are moved to Mail\Spool\Holding.

So I'd check these 3 folders for the msg file referred to in the log, and if it's in holding, delete it from the other folders.
