Hello all
We would like to monitor Postfix mail queues using SMNP so we can receive
alerts whenever the mail queue reaches a certain threshold. What OID and
MIB would we have to use to be able to monitor Postfix mail queues?
Thank you for all of your help in this post and other posts of mine!
Up to you.
