Field "Sender" is blank

[adept]

Hello
I've upgraded Proxmox Mail Gateway till 2.6 and now have a problem with tracking center. (in the past version everything was ok)
In all accepted/delivered mails (incomming and outcomming) the field "Sender" is blank ( in this manner "<>").
In all blocked/greylisted/rejected mails (incomming and outcomming) the field "Sender" is filled. it's ok.
How to fix this problem and have filled "Sender" field anytime?
Screenshot is in attch
Thx

1 and 4: I had proxmox 2.4 FREE. It was running on Proxmox VE. In this October I downloaded proxmox 2.6 FREE. Old version was deleted after local Apocalypse. New version was installed instead. All settings were entered manually again.
3. Version:2.6-4540, downloaded from your site
2. It seems that all services are running, besides Cluster's and Kaspersky)


p.s. I use Proxmox mail gateway with Exchange 2010
