Is the PGP Email Gateway different from PGP Universal Server
I am trying to understand the architecture of the PGP Email Gateway, so far, documentations describe PGP email gateway as a seperate appliance. I would like if this can be verified, or know how the PGP Email Gateway architecture works.
How does PGP Email Gateway handle external users. PGP web/pdf messenger seems to serve this purpose, however, I would like to know how the PGP pdf/web messenger works in handling external users, or at the very least a dcumentation that can explain this explicitly.
