[imp] IMP: Special characters in password "removed/changed" automatically

[Stefan König]

Correcting myself, the transmitted bytes 0xc4 and 0xe4 are OK. I got the
wrong table.
However, this changes nothing about the result of the IMAP server
rejecting the login.
If I login via telnet, everything works perfectly....

thanks again
regards
Stefan
