Both IONET.NET and MERCUR.USAO.EDU are e-mailed directly from [log in to unmask] via its mailer (no distributed LISTSERVs involved this time) and MAILER is sending via the local SMTP machine (the default entry). I suspect some sort of SMTP q reordering on TEMPLE as well as massive amounts of traffic (any SPAMs in progress?). Don't know if MERCUR has undergone any IP address changes or if its MULTINET is responding fast enough (check with their sysadmins to see if there are any timing-out connections from TEMPLE). /Pete Weiss -- Penn State
