Removal of www.instantservers.com (ISMail)

We had a listing titled ISMail in the Category:
http://dmoz.org/Computers/Software/Internet/Servers/Mail/

with a link:
http://instantservers.com/ismail.html

The listing was present for quite some time and is still visible in some caches, but appears to have been removed recently. Could you please tell us why?

Thank you.

We rarely list deeplinks.

Thank you for the explanation.

We used a file name in the link since we have another listing titled 'InstantServers' in the Category:
http://dmoz.org/Computers/Software/Internet/Servers/WWW/

that links to: http://instantservers.com/

Since other sites (with multiple products) also seem to have multiple listings, we thought that this would be acceptable (and we included a note describing the other listing in our original submission for 'ISMail').

Would is be possible for us to re-submit the request for the title 'ISMail' in the Category:
http://dmoz.org/Computers/Software/Internet/Servers/Mail/

with a link to: http://instantservers.com/ ?

Thank you again.
