Technically, that is not the fault of smtplib.SMTP

The standard for SMTP AUTH specifies that characters following "334 " MUST be Base64 encoded.

See , 3rd paragraph:

> A server challenge is sent as a 334 reply with the text part
> containing the [BASE64] encoded string supplied by the SASL
> mechanism.  This challenge MUST NOT contain any text other
> than the BASE64 encoded challenge.

Servers that send non-BASE64-encoded text after "334 " IMO is violating the standards.
