Bob,
Not that I'm aware of. At least they're not using the mail-abuse.org/dul
filter. Look at any bounces you receive from them. Check to see if in
the reason for the rejection it lists a filter service.
I do know that letters from root@localhost bounce. This is a good policy
in that root should only be used for local administration. Otherwise it's
best for system security and stability that a regular user account be used
for normal email and Internet access functions.
If you're using your system as its own MTA your box has to resolve either
through your ISP (best if you have a dialup account) or through a virtual
domain. If you simply gave your PC a name but didn't set up the
configuration with a resolveable domain then mail you send out will almost
always bounce. For example if your ISP is uswest.net, and you named your
machine falcon, your outgoing mail will always show from
falcon.uswest.net. This domain doesn't exist so your mail will usually be
rejected by the recipient mail server.
There are a couple of ways to fix this. The method usually pushed is to
use envelope masquerading. You can do this if you only have one email
address you need to send mail from. If you need a more versatile setup
try the following:
You'll need to set your box up as its own MTA, but do so so that it
resolves back to your ISP. You might try masquerading your machine by
giving it the same name as your user account on your ISP. For example if
you're ISP is bellsouth.net, and you're username (lets use bobt) is on
their red machine your literal address is [EMAIL PROTECTED] You can
masquerade this setup on your PC by giving it the name "red" and in the
network configuration set up your domain as bellsouth.net. Thus your
machine ID becomes red.bellsouth.net. This is a resolvable domain. But
if your ISP is like mine your mail will still bounce unless your username
also matches up, so you need to set us the user bobt on your home machine
and send all your mail out from this user. Thus your outgoing IDENT
becomes [EMAIL PROTECTED] (if you have a dialup account).
This will resolve, and also maintains Internet security in that if you
send out a virus or other destructive mail from your box you can be
tracked down through your ISP's logs by checking time of login with the
dialupXXX. You can use Pine to modify your From: field to any legitimate
return email address you have. Your outgoing IDENT will show
[EMAIL PROTECTED], but your From: field will show whatever
email address you put it.
Some would argue that the above isn't legitimate because you're "lying" by
claiming your local box is the real red.bellsouth.net when it isn't.
Technically this isn't true, as your outgoing mail identity isn't
red.bellsouth.net, but is dialupXXX.red.bellsouth.net, which legitimately
distinguishes your home machine from the bellsouth.net machine. This is a
feature that the Internet has set up for home Linux/UNIX users that allows
us the freedom to run our own MTA's while still making it possible for
those sending out viruses and spam to be tracked down.
