You're right, it was broken:
auth plain b64_encoded_\0user\0pass
535 Incorrect authentication data
It works for LOGIN:
auth login b64enc_user
334 UGFzc3dvcmQ6 <--- what is this, anyway?
b64enc_passwd
235 Authentication succeeded
I have fixed it, it works for PLAIN also now. A stupid question: why
are there two almost identical mechanisms?
