I've just completed migrating my home system from Courier to Zimbra, and we've migrated our corporate e-mail the same way. I use Thurnderbird as my MUA on both Windows and Mac. I keep Thunderbird running all the time on both systems. However, I am noticing inconsitencies in terms of which messaegs are visible in which copy of Thunderbird. For example, this morning, I checked my home (Windows) system, and I did not see any e-mails in my work account since yesterday morning. However, I looked at my Mac copy of thunderbird, connecting to the same IMAP account, and saw an additional 25 messages.
I never saw this behavior using Courier IMAP, so I'm relatively confident that this is something introduced by Zimbra. The question I've got is, is this a bug? Or is there a configuration option we may have missed that could cause / affec thunderbirds IMAP visibility? Is there any particular logs or traces I should be looking at to debug this?
Thanks very much, in advance.
