Hi,
I am trying to implement greylist on my 3 MX servers in which i am
running
qpsmtpd. 2 servers have same MX priority while the third one is a backup.
I am concerned about the negative impact of greylisting since all the three
servers have their own greylist database.
In the second attempt if the sender tries to send the queued message to
another MX (other than the one which it sent first) then it will delay the
delivery of the message even further.
I guess there are only two soultions.
1. Use the same database across the MXs. For this I am planning to use nfs
export. How efficient will it be? My MX servers deliver around 0.15 Million
mails a day.
2. Or store the database in Mysql. But that will require a hack in the script.
I guess someone has already run into it :D
If there are other workarounds for the problem then please do let me know.
thanks a lot,
Bikrant
