The "real" problem is that the ID: <1B01@DHNFHS1> while having correct syntax, is *NOT* a valid ID on the target system. Note that the name 'DHNFHS1' does not match the names of any currently-valid BITNET nodes. So, scan your subscriber-list, and look for '1B01', and remove that ID. The "charlatan" message is issued by 'MAILER@DHNFHS1': 220 DHNFHS1 Columbia MAILER R2.08 R208004 BSMTP service ready. because it received E-mail from 'SMTP@DHNFHS1', i.e., the SMTP-server-machine on that same host, which, in turn, received E-mail from: 050 MAIL FROM:<[log in to unmask]> However, 'MAILER@DHNFHS1' has not been instructed to "trust" that the 'SMTP@DHNFHS1' machine is to be allowed to act as an intermediary in the mail-delivery process. So, the "charlatan" warning-message is issued. 250-<[log in to unmask]> does not correspond to RSCS origin of DHNFHS1 SMTP. You are a charlatan. Contact the "postmaster" at the specific site, and point out this "configuration-problem" to them.
