> *Context*
> Distributed James do not support MailQueue delays making it unusable as a MX server.
> However given a fixed network of suppliers to work with, delays are not an issues, SMTP error just need to be correctly handled.
> retrying without delay could enhance the situation by working around some transient remote server errors. It’s better than not retrying at all (or doing all the retries without delays).
> Given manual intervention, it is possible to correctly 
> *Requirements*
> Such a solution should:
>  - Attempt delivery a single time
>  - Store transient and permanent failure in different mail repository
>  - After a given number of tries, transient failures should be considered permanent
> *Definition of done*
> Write potentially failing mailet integration tests demonstrating the above proposed RemoteDelivery error handling.
