Re: [bug-anubis] username scrambled

[Sergey Poznyakoff]

Hi Cyrille,

Thanks for additional info. You operate Anubis in proxy mode. This
means, it transfers verbatim all commands and responses between MUA
and MTA. Quoting the documentation (chapter 3 "Authentication"):

  proxy
       No authentication is performed.  Anubis switches to the
       unprivileged user and acts as an "SMTP proxy".

(quote ends).

Note "No authentication is performed".
     
Now, your transcript shows:

> [2410] vAOEgw00002410: Y2ZAAW52ZXN0AWDHDGLVBI5JAA== <=> 535 Incorrect 
> authentication data

that means your MUA (not Anubis) send a malformed username to the MTA
and received failure status. So the error is not related to Anubis.
Please inspect your MUA settings and correct them.

Best regards,
Sergey
