We have a subscriber whose posting to one list is being ignored. The mail arrives, but Listserv neither posts it nor returns an error. Since the list is send=private, I'm suspicious of his "from" address being invalid somehow, but messages to me, commands to listserv and a posting to another public list work. His subscription address [log in to unmask] seems to match his "from" address. Here is the incoming posting.... anything look amiss? Thanks.

I have been experiencing problems in my communication with listserv lately... Dear Ning Zhu, BRGM provides boron isotope analysis on a commercial basis. The technique uses specific ion exchange resins for boron extraction and positive ions (Cs2BO2+) mass spectrometry for 11B/10B ratio measurement. Analytical uncertainty is +/-0.2 per mil (on measured delta value). Required sample quantity is dependent upon boron concentration. Analysis is typically done on 10 micrograms of Boron. So, for a solution containing 1 ppm boron, we need 10-20 milliliters. Price is 3575 FF/sample if you provide boron concentration (add 407 FF/sample for boron content determination). Should you need any further information, do not hesitate to contact Dr. Catherine Guerrot at: E-mail: [log in to unmask] Phone: (33) 02-38-64-31-12 Fax : (33) 02-38-64-37-11 Postal: BRGM, SMN/PEA/ISO, Avenue Cl.

The samples are boric acid in water solution. What I want to know is the ratio of B10 and B11, both are stable isotopes. I would appreciate if anyone can provide me information about where to find such a laboratory. Thanks for the help. Ning Zhu
