It will be only from old versions of vpopmail. I'm using 5.3.20 and this test
does not work:

telnet 25
Connected to
Escape character is '^]'.
220 xx.xxxx.xx ESMTP
auth login
334 VXNlcm5hbWU6
334 UGFzc3dvcmQ6
user invalid username:
535 authorization failed (#5.7.0)

But it's very interesting to know this issue...
