Sounds painful. :( Could the blank emails and greylisting be anything todo with 4psa and plesk 9.2.1 not playing nicely?

I had a look on the 4psa site so see if anyone had mentioned 4psa working with plesk 9.2.1, however, all quiet there. It says it works with plesk 9.x.

I’ve not yet tried 9.2.1… bit worried about bugs still.

bugs i appear to have are….

plesk handlers now mounted on tmpfs which causes MIME unpack errors.
blank emails containing the word DROP when using spamassassin (4psa spam guardian)
greylisting -tried to switch caused some ridiculous error, no idea if its even working
