I'm hoping this thread can be a new gathering point for SmarterMail users and admins who are still experiencing the IMAP mailbox corruption problem that we and others have experienced from SM5 through SM7, and Windows2003 through Windows 2008*. We currently have a ticket open with SM Support and they have agreed to develop a build of SM7 with advanced logging enabled that will supposedly help them track this issue down. Since the corruption happens for us only about every other month, it will most likely be time consuming to generate enough data to debug this -- meanwhile our users and presumably yours are vulnerable to this. I'm hoping that others will be interested in running this advanced logging build, which SmarterMail developers assure me will be completely stable. If enough of us are able to help, they should be able to track down the issue far more quickly. Smartermail has told me they will make this build available to anyone who requests it. Are there any users out there that have experienced this in the past, or are still experiencing the issue now and want to help? *To be clear, I am talking about IMAP mailbox corruption, usually in the form of messages dissapearing from the inbox or showing up with a blank subject line and no data in the e-mail. Often the e-mail view within webmail will say that the message has been deleted from the server, although there is still a message pointer in the Inbox. It will usually be clustered in one day, or over several hours of one day due to SmarterMail arranging each days messages in a seperate .grp file.
