[comp.mail.misc] ! vs @ Precedence

matthews@udel.EDU (John Matthews) (02/22/89)

Could some please give me some pointers to where a standard might exist that
says that I should parse addresses like this:

	node1!node2!node3!user@machine.xxx.edu
	[   ^ ^ ^ ^ ^ ^ ^ ^ ^ ]  go to machine.xxx.edu first.

	instead of

	node1!node2!node3!user@machine.xxx.edu
	     [ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ] pass this address to node1 first


I always thought that the first was always the way to go, but I have seen
mailers at Bell Labs doing differently.   Which should always have highest
precedence?   Please feel free to point me to any RFCs that contain this
information.

Please respond to m here at udel with "matthews@udel.edu".  I don't always
get a chance to keep up with all of the newsgroups.

From article <9293@louie.udel.EDU>, by matthews@udel.EDU (John Matthews):
 
  *  node1!node2!node3!user@machine.xxx.edu
  *  [   ^ ^ ^ ^ ^ ^ ^ ^ ^ ]  go to machine.xxx.edu first.
 
 	...or

  *  node1!node2!node3!user@machine.xxx.edu
  *       [ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ] pass this address to node1 first
 

RFC976 sez that mixed mode addresses should be avoided, but that the 
first example above is the prefered one.
