<li>Please remember we only know

|
what is posted in your message. Do not leave out any information
|
|
|
|
|
|
that appears to be correct, or was mentioned in a previous
|
|
|
|
|
|
post. There have been countless posts by people who were sure
|
|
|
|
|
|
that some part of their configuration was correct when it actually
|
|
|
|
|
|
contained a small error. We tend to be skeptics where detail
|

is lacking.<br>

Any help we offer is an act of generosity, not an obligation.
|
|
|
|
|
|
Try to make it easy for us to help you. Follow good, courteous
|
|
|
|
|
|
practices in writing and formatting your e-mail. Provide details
|
|
|
|
|
|
that we need if you expect good answers. <em>Exact quoting </em>
|
|
|
|
|
|
of error messages, log entries, command output, and other output is
|
|
|
|
|
|
better than a paraphrase or summary.<br>

us to send you custom configuration files. We're

<blockquote> A growing number of MTAs serving list subscribers are
|
|
|
|
|
|
rejecting all HTML traffic. At least one MTA has gone so far as to
|
|
|
|
|
|
blacklist shorewall.net "for continuous abuse" because it has been
|
|
|
|
|
|
my policy to allow HTML in list posts!!<br>
|
|
|
|
|
|
<br>
|
|
|
|
|
|
I think that blocking all HTML
|
|
|
|
|
|
is a Draconian way to control spam and that the ultimate
|
|
|
|
|
|
losers here are not the spammers but the list subscribers
|
|
|
|
|
|
whose MTAs are bouncing all shorewall.net mail. As one list
|
|
|
|
|
|
subscriber wrote to me privately "These e-mail admin's need
|
|
|
|
|
|
to get a <i>(expletive deleted)</i> life instead of trying to
|
|
|
|
|
|
rid the planet of HTML based e-mail". Nevertheless, to allow
|
|
|
|
|
|
subscribers to receive list posts as must as possible, I have now
|
|
|
|
|
|
configured the list server at shorewall.net to strip all HTML from
|
|
|
|
|
|
outgoing posts.<br>

|
|

|
|
|
and it doesn't have a valid DNS PTR record, your email won't reach the lists
|
|
|
|
|
|
unless/until the postmaster notices that your posts are being rejected. To
|
|
|
|
|
|
avoid this problem, you should configure your MTA to forward posts to shorewall.net
|
|
|
|
|
|
through an MTA that <u>does</u> have a valid PTR record (such as the one
