I've got a rather weird problem with one of my Zimbra installs - certain users are unable to send messages with attachments. The affected messages will save to their drafts folder, and they can be opened and appear correctly, yet any attempts to send them results in a message like this one:
It seems this happens only when forwarding or replying to a message, sending a message from scratch works fine. I've tried reindexing the mailboxes of affected users, to no avail.
msg: no such message: 1144
data: [object Object]
trace: com.zimbra.cs.mailbox.MailServiceException$NoSuchItemException: no such message: 1144 Code:mail.NO_SUCH_MSG Arg:(itemId, IID, "1144") at com.zimbra.cs.m...
Any ideas how I can solve this?
