Re: subscribing problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


I was able to subscribe to the Linux-hotplug list in less than 15 seconds from 
my office location.  No problems or delays at all.   Using the same email 
address, mail server, authentication, etc.  With the only difference being 
the originating IP address of the workstation.  

The first was from home and the second was from the office.  The office 
network is on the same network as the mail server.  My home uses a different 
service of course.  I run two computer systems with identical mail systems 
duplicating all incoming mail messages between the two systems, home and 
office.  I use authentication on both, the home system requires 
authentication for my mail server to relay but the office system does not 
really require authentication since it is the local network.

I have to conclude this greylisting policy is looking at the origination IP 
address and if it is different than the mail server network then it is 
blocked unless it is authenticated.  But the test for authentication is not 
reliable.  Hence, I had to send six mail messages from home to get two of 
them delivered!  So this new system is not all that it should be.
