Lost mail 2.3.8

[Casper]

Hello, i have a murder setup.

And som user say that they sometimes not recieve mail the send.

The log on smtp (with lmtp delivery to the imap server) say it got the
mail and sent it to cyrus (sendmail mailer Mcyrus).

The imap server say it got the mail and stored it.


But the user never gets the mail.

I use 2.3.8.

Does anyone know if this is a bug or what tha he** this is...

All logs say the mail are stored.
