acquired the software with: wget http://openwebmail.org/openwebmail/download/release/openwebmail-2.52.tar.gz followed by many wget's of required perl modules and such and installed the lot. I recall rounds of configure,make,make test,make install for the perl modules. I don't recall doing that for the openwebmail, I do remember "./openwebmail-tool.pl --init" after some config file changes. I'll check those specific settings. If the message had been held I should have seen an entry for it in the vette log and there wasn't one. I checked the message header for an Approved line and (fortunately) didn't find it. I'd be very "disappointed" to find that password in a message header. I'll keep poking at this end. I'd love to hear any other ideas... -- Steve ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
