that some part of their configuration was correct when it actually

courteous practices in writing and formatting your e-mail. Provide

that we need if you expect good answers. <em>Exact quoting </em> of

<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 convert all HTML to
|
|
|
|
|
|
plain text. These converted posts are difficult to read so all of us
|
|
|
|
|
|
will appreciate it if you just post in plain text to begin with.<br>
