Hello, after installing Zimbra and synchronizing with my Yahoo account, I noticed that many mails are linked automatically, creating some sort of threads featuring an arrow on the left and the number of mails included on the right. To say the truth, this feature is not very convenient for me, but one can get used to everything. The thing is that in many cases it just links mails that have nothing to do one with the other, creating a huge mess. I was looking for quite a while for a certain mail until I found it by coincidence under a message it has nothing to do with (the email addresses are not even close, so I donít understand why they were related to begin with). Is there any way to undo this linkage thing or disable this feature?
