My interpretation of the error message that you asked about is that the subscriber's e-mail system, network or possibly PSUVM.PSU.EDU itself was unavailable for at least 4 hours.

Maybe there were some process config problems at: >from Cust6.Max45.New-York.NY.MS.UU.NET [153.35.22.6] >Reporting-MTA: dns; germany.it.earthlink.net -- co-owner: INFOSYS, TQM-L, CPARK-L, ERAPPA-L, JANITORS, LDBASE-L, et -L URL:mailto:[log in to unmask] "PSUVM.bitnet RIP 12/31/96"
