[kropla]

Hi
i am quite fresh on proxmox mail sollution
anyway
i configure my mail gateway (its worked ) - but in my opinion greylistining not workinkg. In the option of Mail Proxy i have set parameter called:
"Use greylistining for ipv4" to TRUE .
currenty i send mail from domain that never comunicate with this Mail Gtw ... and i have an email immidietly. I thought that i need to be bold for 5 minutes (and i hope that this i should work exacty that) .
can you tell me what should i set ?

yes, valid senders (SPF) should not be greylisted.
