This is how most mail systems handle user name validation: they don't
validate anything at composition/submission time, and let
erroneously-addressed messages get mailed back to the submitter.  You
can achieve these semantics with AMS by disabling the validation of
addresses as you see fit, generally in one of the AndrewSetup files. 
The setup.help file describes the validations.

In brief, there are two kinds of things getting validated: local user
names and remote mail destination names.  Local user names are validated
according to the settings for the options:
	AMS_WPValidation
	AMS_PasswdValidation
	AMS_LocalDatabaseValidation
	AMS_AliasesValidation

(Non-local) destination mail domain names are validated according to the
settings for the options:
	AMS_ValidateDestHosts
	AMS_HardHostValidationErrors
	AMS_DeliveryViaDomainMXAddress
	AMS_DeliveryViaDomainAddress
	AMS_DeliveryViaGethostbyname
	AMS_DeliveryViaHostTable

To turn off validation of local user names, set all the
AMS_xxxValidation values to zero.  To turn off validation of remote
destination mail domain names, set AMS_ValidateDestHosts to zero.

Once this is done, validation will happen only in the mail delivery
agent, which you can generally get to mail error messages back to you.

Maybe it's only one part of the recipient validation that's taking a
long time, or something that's slightly mis-configured for your
environment.  Validation is supposed to be fast enough that you're
willing to have it tell you right away if you made a typing mistake, but
if it's getting in your way, turn it off.
