I would try to figure out which mechanism is marking those e-mails as spam and why. You could try to see that by showing "original" mail and see the spam scores and/or by watching the mail pass thru your /var/log/zimbra.log

Also, as you are using thick clients like outlook, make sure that the one marking those mails as spam is your server and not those thick clients.

In regards of your question, I guess you could go with spamassasin general tunnnings like the ones explained here: https://wiki.zimbra.com/wiki/King0770-N ... sassin-MTA
Or maybe trying to do it via user whitelisting under preferences.

In any case, before start trying how to add exceptions and whitelists, you should see why those mails are marked as spam and which daemon/system is marking it. Usually whitelisting is not a good long term solution and is usually better to train your spamfilter (in case that's the one marking those mails as spam).

reasons why that's being blocked are self explanatory. You could try to change that or change the scores those assignt to a negative value in your sauser.cf maybe.

But, maybe marking those mails as non-spam and training your spamfilter fixes this for you?

You've already been given the answers to those questions. Look at the scores in the "X-Spam-Status" and then read the links that have been given to you, that explains the scores.
