The respones, wich was in Swedish (included) and they basically state that they don't understand the problem, they don't care and if there are recomendations for things like 'postmaster' they would ignore them. They also talks something about x.400 that does not mame any sence to me.

P} vilket s{tt upptr{der TELIA som OPERAT\R i nedanst}ende inl{gg ? Jag uppfattar detta som en typiskt exempel p} vad du brukar beteckna som 'anv{ndare' i Internet, och ett exempel p} vilka problem man kan r}ka ut f|r n{r man anv{nder DNS f|r att direkt routa post till slutanv{ndaren, TELIA MOBITEL i detta fall, utan att anv{nda n}gon ansvarig kommersiell OPERAT\R ! Man skulle ocks} kunna betrakta det som ett fall d{r TELIA.SE upptr{der som 'operat|r' (j{mf|r PRMD) och f|rmedlar post till TELIA MOBITEL (som {r ett eget f|retag). I b}da fallen belyses problemen med det distrubuerade ansvar som finns inbyggt i DNS, och d{r det kan vara sv}rt f|r en avs{ndare att hitta en ansvarig representant f|r mottagaren i de fall kommunikationen av n}gon anledning ej fungrerar. Det visar ocks} p} behovet av att kunna skilja p} TELIA som e- post operat|r och TELIA som anv{ndare av e-post, vare sig detta sker i Internet eller i X.400 v{rlden, Ett bra s{tt att g|ra detta p} {r att anv{nda OLIKA dom{nnamn (och olika interna system) F\R DE OLIKA FUNKTIONERNA. T.ex. 400net.se (Telia/Unisource som operat|r i Sverige) respektive unisource.se och telia.se i 'anv{ndarfallet'. mvh/bernt --------- (2.027.610) S|ndag, 10 jul 1994 14:23 Peter Lothberg <[log in to unmask]> Mottagare: ag12 <[log in to unmask]> Mottagare: Bernt Allonen Privat -- Mottaget: Tisdag, 19 jul 1994 20:39 [rende: [Mike Ramundo <[log in to unmask]>: unknown node: SPARCY.MOBITEL.TELIA.SE] Telia, den seri|sa operat|ren..... ----------------------------Original message---------------------------- I have been getting several requests per day from this person - commands always correct but return address unknown.
