Situation
Summary: IMAP client "save as draft" circumvents file size
limits and can cause the host File System to fill up
completely.
Steps to duplicate:
Set up Thunderbird mail client pointed to GWIA IMAP
server.
Compose a new message and add a 2GB or larger
attachment.
Save the message as a draft.
/wpgate/gwia/000.prc/gwwork folder will show a file created
that will grow to more than 2GB in size. The client may throw
errors and it seems that each time it does a new file is created in
the gwwork folder that will also grow to more than 2GB in size.
This repeats until the disk if full.
Note: This doesn't happen if the mail client is
configured to store draft messages on local drives. However
the default is to store drafts on the IMAP server. This
leaves us in a vulnerable situation as a single user can bring down
the GWIA server by trying to email a copy of the latest Marvel
Avengers movie.
Resolution
This has been resolved in the shipping GroupWise 2014 R2 SP2 and newer. The fix is also in shipping GroupWise 18 and newer
