Anyone else using Postfix + SmarterMail

[James Chase]

We have an issue with our SmarterMail mailboxes, especially via IMAP 
connections, where messages will become corrupted and/or deleted from 
the server. Just curious if there was anyone else out there also using 
Postfix and Smartermail together who has experienced the same sort of 
issues, or if you used SmarterMail in the past, what you are using now...
