A customer uses a dial-up ISP (netcom.ca) that allocates a dynamic
IP address and a Netscape 4.61 client to send mail. The mail sender
is actually dchill@???, so that is how his netscape client is
set up. This is a test message to himself. The mail should be
delivered locally on our server for collection by POP3 or IMAP.
Messages from the outside world are working but the user can not send
mail to themselves. Although netcom.ca is in the imrss.org RBL it is
only in warning mode and not in reject mode, so this is not the issue.
I can work round the problem by adding an entry
sender_verify_hosts = "! lsearch;/usr/exim/local/unverified_senders"
where
unverified_senders contains a reference to 'tor-smtp2.netcom.ca'
but this is far too manual and I would like to get it fixed generically
as otherwise I will have to fix this each time a new customer with the
same problem comes along. Also I can't control what changes may take
place within netcom.ca and I am not even sure that this is their
only mail gateway
