Horrid E-mail addresses

• /RFC-822=(q)$/G$=Thomas(u)Schimana(a)p31$/S$=BaBaBoX.IN-Passau.DE$/C$=IN-Passau$/(q)(a)choose.a.gateway.please/O=nac/PRMD=uninett/ADMD=/C=no/ is a grand example of what happens if you map an Internet address to X.400 to Internet to X.400, without understanding that it is an Internet address. (There should have been a space in the ADMD field, but this causes the line to break)
• remote-printer.Dirk_Haussmann/Geschaftsfuhrer@2.4.3.5.7.3.2.7.5.0.9.4.tcp.int is a wonderful way to address a fax machine, isn't it?
• SOME_USER@HP-SWITZERLAND-desk1////////HPMEXT1/THIERRY#b#PARIDANT#o#HP8700#o#Y0.om.hp.com apparently worked, too!
  I don't know if the even more amazing 'KIDO'/HPJPN_UM////////HPMEXT1/kido#p#vnet#f#ibm#f#com#a#relay#f#jpn#f#hp#f#com%opnmail2.corp.hp.com@hplb.hpl.hp.com has a snowball's chance of working, but at least here most of the damage is done on the lefthand side.
• GIS_+a_RCI_+lGivenname_Surname+i%MHS+d_20D08E2B01F53FDC-20D08E2B02F53FDC%RCI_Incorporated@mcimail.com couldn't be used for replying.
• For.a.prompter.reply.please.fax@IF.YOU.DO.NOT.HAVE.A.FAX.SMAIL.IS.OK is an example of people putting something into an addressing field without really thinking through the implications.
• NONE.REALLY@Help.me.get.one! is another interesting variant of "this is not an E-mail address". This is often seen on news-to-mail gateways; news doesn't really care if the FROM field is replyable or not.
  Another variant, but with opposite meaning, is Ask@I.don't.want.to.be.spammed (also from a newsgroup).
  But spam with do_not_hit_reply@do_not_hit_reply for a return address is simply a spammer who KNOWS that his From: account will be dead before he gets a reply back.
• S=ghosh%S=ghosh%C=IN%P=XEEMAIL%O=XEEPNQ%OU1=HQXEEOPN%VSNL@mcimail.com clearly demonstrates why RFC 1327 is needed; there ought to be a limit on how hard you work at making addresses look broken when the base system once had a relationship to X.400...
• Deliberate abuses of host naming can be found in names like edu.com.gov.org.mil.net or the fact that dockmaster.ncsc.mil.net and dockmaster.ncsc.mil are two different hosts.
• On the other hand, clark@YingTongDiddleiPo.ee.wits.ac.za is probably just an example of a machine name being picked at a time of high humor.
• The machinations of people who don't understand what a domain literal is never cease to amaze me; what was the person who configured his E-mail address to be timch.pedagog.sortland_vgs@158.39.105.2 thinking of?
