Looking at an installed system here and following your and Gabriel's
reply it would look like we should increase the minimum requirement to
2.5 GiB and keep 4 GiB for recommended minimum ones.
As the minimum requirement basically should cover the needs to get
it installed and up and running. I did some heavy testing with millions
of mails per day on PMG installations with 4 GiB of memory, worked out
fine. One of our production PMGs also has just 4 GiB total memory, while
the other has 8 GiB but hovers around 3.8 - 3.9 GiB usage, so I really
do not see why we should increase the recommended memory to 6 GiB...
