There is a known bug in version 1.2.0.178 of SpamFilter.  It is listed as fixed in 1.2.0.197 (where indicated with asterisks)

// New to VersionNumber = '1.2.0.197';
{DONE -cFix : Memory leak issue with certain malformed subject headers}
{DONE -cNew : Better handling of non-RFC emails from FedEx robots}
{DONE -cFix : Fixed extra "dot" command at end of transmission}
{DONE -cNew : NT4 without MDAC is now able to run SpamFilter (without quarantine option)}
*****{DONE -cFix : Fix for the deliver and delete quarantine buttons remaining grayed out}*****
{DONE -cFix : Returned non-deliverable emails to sender now sent to "Reply-To" header rather than "Mail from"}

There is a considerable amount of e-mail that has gotten caught up in the spam-filter and I no longer have a way to push it through due to this bug.  This is a serious problem, and I am wondering if it may be possible to download a later evaluation version that 1.2.0.178 (does not have to be the latest--just 1.2.0.197 or later) so that I may continue my evaluation of your product?

If this is not an option, would you please tell me how I might go about retrieving the e-mail that I can no longer push through because the deliver and delete quarrantine buttons are greyed out?  Thank you!

Thank you!
