I know this is not a good description of the problem, but it's all the info I have.
My user (my boss actually) received a forwarded email (with an attachment in it ) and he could get it in Zimbra web interface, but could not get it in Thunderbird. (Yes, I know I should test using another email client like Outlook etc.). Another user also had a similar problem.
I don't know if the problem is with Thunderbird - but we didn't have problems with Thunderbird when we were not using Zimbra imap server (we used Sendmail/Imap-uw server previously). Maybe Thunderbird has some issue with Zimbra imap server ?
Does anybody here have a similar problem ? Any idea how to resolve?
Thank you very much in anticipation.
