Well, I'm trying to learn how to be a responsible listowner and to deal with error messages. For some time now (?2months) I've been getting bounces from @BBL.PSYCHA.UPENN.EDU saying stuff like: >VTBIT.CC.VT.EDU unable to deliver following mail to recipient(s): > <[log in to unmask]> > <[log in to unmask]> > <[log in to unmask]> > <[log in to unmask]> >VTBIT.CC.VT.EDU unable to connect for 7 days to recipient host. I unsubbed them once, and they re-subbed (which is fine). Unfortunately, the bounces continue. I've sent mail to postmasters: to: [log in to unmask]: > ----- Transcript of session follows ----- >421 psycha.upenn.edu (tcp)... Deferred: Network is unreachable and, to: [log in to unmask] >---- Transcript of session follows >%UCX-E-SMTP_SNDERROR, Error detected while sending mail to ><[log in to unmask]> >-RMS-E-RNF, record not found >---- Recipients of this delivery ---- ><[log in to unmask]> (bounced) and these bounced. I've also looked up the contact at UPENN.EDU: >whois upenn >whois psycha and found [log in to unmask], (but John has not responded--his InterNIC listing was last update in 1991). Any recommendations as to how I should handle this? (I have a similar problem with an address at NIMH, but I hope to be able to apply whatever strategies I learn from the UPENN problem.) Thanks.
