Hello Charles,

I disagree here.  Look the three examples for host 'boell' I've typed a
wrong password, host 'krampus' (a MS$ one) does not run SSH daemon and
host 'krampuss' just does not exist:

$ ssh boell
guru at boell.sisis.de's password: 
Permission denied, please try again.

$ ssh krampus
ssh: connect to host krampus.Sisis.de port 22: Connection refused

$ ssh krampuss
ssh: Could not resolve hostname krampuss: hostname nor servname
provided, or not known

These are the normal world responses, at least of a SSH client in
FreeBSD; I don't see any security hole, but in any of the three cases
you know the error which has occured.

In the Exchange authentication fields of Evo (Edit-->Preferences-->MailAccount)
I have to set following the advice of the server admins:

Username: OCLC\apitzm

I have no access to the Exchange server, but will check your hint with
the admins there.

Thanks for your kind help and I will let you know, of course

People who hate Microsoft Windows use Linux but people who love UNIX use FreeBSD.
