[UA-EAI] UASG014 - Quick Guide to EAI

[Don Hollander]

Arnt, John:

Thanks for these comments.  

When a set of mail applications are bundled under a single umbrella, then the operator can do more - and the Transformation using an existing Alias is possible.

But, if a mail user is using discrete components, then can you reasonably expect them to interact as we suggest transformation?

Are we back to square 1' - having eliminated an algorithmic transformation of a non-ascii mailbox name?

    That sort of fallback mostly makes sense in a webmail system where the MTA 
    and MSA and address book are sufficiently integrated.
    
    To do it in postfix or exim you'd need to add an MTA-side address book of 
    aliases which is rather unlike anything they do now.  I use qmail which 
    can easily tell whether addresses A and B deliver to the same place, but 
    cannot tell you the other addresses that deliver the same as A, which is 
    what you need here.
