Thanks Lyle

The 421 being given by the Yahoo servers is as a result of ongoing 550
errors.

On receiving a 550, surgemail retries sending a number of times - only
producing more 550 errors - legitimately.

This continues until Yahoo servers temporarily deny emails being sent from
my server preventing real email being sent.



How do I stop surge mail retrying 5xx errors ???
