[plug] Why don't my messages get through?

[blockley at environ.wa.gov.au]

Thanks Everyone for the replies,

It turns out that things are a little more complex than I had first
thought and than I mentioned in my original post.

The computer from which I originally subscribed (an old Sparc 1)
finally died.  All the network services it was providing were moved to
another machine that had a different name and an alias provided for the
new machine so that mail sent to the old address would still find a
home.

So far I think this is fine and it is no problems to change the from:
field in Pine.  Oddly enough my posts were still not getting through. 
I decided to unsubscribe my old address and resubscribe as my new
address. 

First I try setting the From: field to blockley at central.murdoch.edu.au
and unsubscribe. I get the message that blockley at central.murdoch.edu.au
is not a member of the list.  Now this is ok because I knew that this
probably wasn't my original subscribed address but I wanted to make
sure that I was putting my address in the correct place.

I change the From: field to blockley at atmos.murdoch.edu.au (which I am
certain is the correct address) and again try to unsubscribe.  This
time I get a message telling me that blockley at qnim.murdoch.edu.au
is not a member of the list.  It looks like the address on my From:
field is being filtered so that if I use the atmos address it is being
changed to qnim if I use another address it is not being changed.  Is
this filtering typical for aliased host names?

I finally tried 

unsubscribe plug blockley at atmos.murdoch.edu.au

This at least got as far as telling me that I was trying to unsubscribe
from a different address than which I originally subscribed and that my
message was being forwarded to the list maintainer for him to decide
whether I can unsubscribe.

This has been a lot of effort...

Cheers

Adrian
