What do you think is the benefit of this feature? Is there any "normal"

I think a gateway solution should not weaken the security of a
desktop-to-desktop scenario, in situations it is not necessary in. I use
a gateway scenario, because I want to benefit from the advantages like a
centralized archive, an enforceable security policy and the transparency
in front of my users. On the one hand I share your opinion, that in general
you should assume to trust your internal infrastructure, but on the other
hand there may be employees with different responsibilities which may not
share same trust level.

I have noticed, that other products refuse to decrypt messages in such a
scenario. I just wanted to make sure you are aware of this feature and
wanted to hear your opinion about it.

Kind Regards,
