What is it, why is it so?
They're checking whether they can get bounces back to you and, if not, they'll reject your mail. It looks like your mail server rejects mail with a null sender--this is a very bad thing to do and will land your domain in blacklists such the ones run by rfc-ignorant.org.
How to fix it??? It is a standard SuSE 8.0 prof And, if they test if it bounce, but than I receive the message though! How can I test that feature by myself? How do they do that? bye Ronald -- Ronald Wiplinger, Technical Director Bright Networking Inc, http://www.2bright.net 7F, 192-1, Sec. 3, Tatung Rd., Shijr City, Taipei, Taiwan, RoC Tel.: +886 2 8647-1685, Mobile +886 915 653-452, Fax: +886 2 8647-2002
