SASL PLAIN authentication failed: no mechanism available

[sellotape]

Hi.

I've tried the guide here: http://www.howtoforge.com/ubuntu-11....nism-available

However have had no success - I am still receiving the error message:

SASL PLAIN authentication failed: no mechanism available

I'm not sure what to do next to get this working - any help would be appreciated.


Many thanks
