I recently got notice from IETF mailing lists that my mail has been

Those bounces are delivery problems, see below why.
so I couldn't get any clue what is wrong. However, now I got a bounce
notice from bugtrag.. and it had this note
[..]
Apparently "networksolutions" for some reason occasionally resolves
"burp.tkv.asdf.org" into "resalehost.networksolutions.com".
Ever though about the place where bugtraq is hosted?
Also note that the IETF has nothing to do with that.
Isn't this behaviour totally antisocial from networksolutions and how
can it be stopped?
Antisocial is accusing organizations. Do a dig and find out:
org. 172800 IN NS TLD3.ULTRADNS.org.
org. 172800 IN NS TLD4.ULTRADNS.org.
org. 172800 IN NS TLD5.ULTRADNS.INFO.
org. 172800 IN NS TLD6.ULTRADNS.CO.UK.
org. 172800 IN NS TLD1.ULTRADNS.NET.
org. 172800 IN NS TLD2.ULTRADNS.NET.

Now ask gw1.solid.fi where the NS is, eek a NS -> CNAME, that violates
some RFC's:
$ dig @gw1.solid.fi ns.tkv.asdf.org.
;; ANSWER SECTION:
ns.tkv.asdf.org. 86400 IN CNAME tkvnic.tkv.asdf.org.
tkvnic.tkv.asdf.org. 48291 IN A 212.16.100.33
And that host is not alive. So the MX can't be resolved, nor the A
record of "tkv.asdf.org" and as such mail will bounce.
Conclusion: Fix your mail setup.
Instead of accusing other people of things they don't do.
