If you rewrite the strings, the issue becomes clearer:

hafi news hafi 1.open-news- hafi network.org hafi
hafi read hafi .news.telefo hafi nica.de hafi
hafi news hafi .alice-dsl.d hafi e hafi
hafi free hafi news.netfron hafi t.net hafi
hafi news hafi .tota-refugi hafi um.dehafi
hafi news hafi .online.de hafi

So in between "hafi"s there are parts of certain lengths (4, up to 12,
rest) of the old account name, and "hafi" is both at the beginning and
end of all strings.

As I already noted on the newsgroups (somewhere...), I've seen this bug
years ago but was never able to reproduce it. Thanks to your list of
broken strings (heh) I was able to track it down this time: I'm 99% sure
nsMsgIncomingServer::OnUserOrHostNameChanged is the culprit. As the name
implies, a username or password change triggers a renaming of the
account name (prettyName internally): "replace all occurrences of old
name in the acct name with the new one". It seems the code is not always
doing the right thing (maybe if oldName or newName are empty?). Do you
remember what exactly you did and what you entered?

In any case I'm pretty sure the issue you see is not this bug, so please
file a new one (Product MailNews Core), CC me and post the bug number
here for reference (I'm not a back-end guy so we'll need help there).
Thanks!
