the config.txt for RCVPNL v0.14 says this:
Reverse DNS incoming IP addresses: enabling this setting will take the
IP address of the remote server and perform a reverse DNS lookup on it.
The reversed information will be placed where UNVERIFIED would usually
be in the Received: line. Enabling this setting may slow the
performance of the server if your DNS servers are particularly slow.
Additionally, Windows has this annoying habit of attempting to resolve
the computer name using NETBIOS if no reverse DNS data is found. If you
see single all caps names in the place where UNVERIFIED would usually
be, this is what happened.
It reads to me like it just logs the result from a reverse lookup, but I
have never used that option, so I cannot say from experience.

On another topic entirely, what is the purpose of the "reverse dns
incoming address" tickbox in RCVPNL. I know what a reverse dns lookup
does - finds the host name for an IP address - but how is it used
RCVPNL/ SMTPRCV? Does it check that the address is a valid MX address
or what?
I'll let someone else answer this.
Haven't got the code in front of me. I'll answer next week if noone
else gets in first (I'm on holidays at the moment).
