I stand corrected:  UTA.EDU distributions to .IE are more than likely
traversing:

INDIGO.IE                      goes to LISTSERV.HEA.IE (733)
 LISTSERV.HEA.IE: UGA.CC.UGA.EDU PLUM.EASE.LSOFT.COM SEGATE   LISTSERV.JA.NET
 LISTSERV.HEA.IE

Note that SEGATE is Bitnet which might imply an Internet-Bitnet gateway
via interbit.cren.net aka

 220 PUCC.Princeton.EDU running IBM VM SMTP V2R4 on Fri, 17 Apr 98
13:11:39 EDT

I just sent a THANKS command to each of the LISTSERV backbone sites:

To:      listserv at UGA.CC.UGA.EDU, listserv at PLUM.EASE.LSOFT.COM
         listserv at SEGATE, listserv at LISTSERV.JA.NET

and they all respond poste haste.
