server: 11.0.2
A pretext for the question. Users with laptop complain on email double send. What I mean, since I map Thunderbird "sent" folder to server "Sent Items" (IMAP), every time they send an email, it gets uploaded twice - to SMTP server and then to "Sent Items" folder on our scalix server. Usually, no one cares until they send attachment of 5-10MB. Couple it with slow connection - you got an unhappy employee.
So my solution is to setup every thunderbird on notebook with BCC field (with owner email) and add a rule on the server to file these emails to "Sent Items" folder. And disable Thunderbird IMAP sync with "Sent Items" folder on the server.
The rule should look something like this:
If sender "me" and to/cc fields are NOT "me" file message to "Sent Items" folder.
Simple right, however... I can not use SWA rules wizard since it does not have negating option. MS outlook has all right things but does not do anything. And I don't know how to combine two conditions using SXAA.
Any help? Thanks in advance.
