    <![CDATA[<strong>Author:</strong> <a href="https://www.logsat.com/spamfilter/forums/member_profile.asp?PF=21">JimMeredith</a><br /><strong>Subject:</strong> 967<br /><strong>Posted:</strong> 20 June 2003 at 8:11pm<br /><br /><P><FONT face="Times New Roman, serif">The "invalid html tags" RegEx keyword has been working *almost* perfectly, but there have been a few situations where legitimate emails are being bounced by this rule.</FONT></P><P><FONT face="Times New Roman, serif">Here's what appears to be happening.&nbsp; If a message contains a forwarded message within its text, this forwarded message text is likely to include the original from/to email addresses.&nbsp; In many cases, these email addresses&nbsp;are enclosed in &lt;&gt;'s.&nbsp; For example:</FONT></P><P><FONT face="Times New Roman, serif">To: &lt;</FONT><A HREF="mailto:longusername@earthlink.net" CLASS="ASPForums" TITLE="WARNING: URL created by poster. "><FONT face="Times New Roman, serif">longusername@earthlink.net</FONT></A><FONT face="Times New Roman, serif">&gt; </FONT></P><P><FONT face="Times New Roman, serif">This matches the RegEx keyword criteria of &#091;a-zA-Z0-9&#093;{11,} so... bounce!</FONT></P><P><FONT face="Times New Roman, serif">To get it working, I've changed the &#091;!--&#093;* portion of the RegEx keyword (<STRONG>zero</STRONG> or more occurrences of !--) to instead read &#091;!--&#093;+ (<STRONG>one</STRONG> or more occurrences).&nbsp; This is still very effective, and&nbsp;has eliminated the&nbsp;bounces of legit messages...&nbsp;but is obviously not perfect as it doesn't offer protection from invalid html tags that are not comments.</FONT></P><P><FONT face="Times New Roman, serif">RegEx is new to me, but I might try working with it later and coming up with some sort of logical NOT based on the occurrence of a @ within the string.&nbsp; If someone&nbsp;more&nbsp;familiar with RegEx could just fire this out and post it here, that would be even better. :)</FONT></P><P><FONT face="Times New Roman, serif">Jim</FONT></P>]]>

The code was not as stable as we would have liked, so we created and made public our beta test versions so that we could have more users test the application and report problems. Had we released an official release it would have been with several bugs, and would have many&nbsp; many users complaining of crashes. We really did not want that.</P><P>After two weeks of testing we finally seem to have a much more stable product. Unless any major problems arise in the next few days, we are thinking of making this beta official by the end of this week.</P><P>Roberto Franceschetti<BR>LogSat Software</P>]]>
