<para>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.</para>

<para>Please keep in mind that you're asking for <emphasis

role="bold">free</emphasis> technical support. 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.
|
|
Exact quoting of error messages, log entries, command output, and
|
|
other output is better than a paraphrase or summary.</para>

<para>Please don't describe your problem as <quote>Computer A

<para>Please give details about what doesn't work. Reports that

|
|
if ping from A to B fails, say so (and see below for information about
|
|
reporting <quote>ping</quote> problems). If Computer B doesn't
|
|
show up in <quote>Network Neighborhood</quote> then say so. If access

<title>When using the mailing list, please post in plain text</title>
|
|
|
|
<para>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 <quote>for continuous abuse</quote> because it has been my
|
|
policy to allow HTML in list posts!!</para>
|
|
|
|
<para>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 <quote>These e-mail admin's need to
|
|
get a (expletive deleted) life instead of trying to rid the planet of HTML
|
|
based e-mail</quote>. 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.</para>
