Our corporation has various e-mail security filters / features in place. The net result is that i.e. every e-mail with a jar file or a class file attached is getting filtered out and held back and is not delivered to the user by a primary DL-Antigen filter. and regarding jar's and classes, even security personal can after that not forward such e-mails because a second level local DL-Antigen filter helds back such jars and classes attached. As a frequent reader, I am missing that way many interesting answers or topics.
To speak for myself, I whish that you do not attache classes and jars ... again speaking only for myself. Thank you, Josef
