Thanks Valdis -- I thought that it might have been something to do with

where the error codes were appearing.

Thanks,

Jim

The 5.0.0 is an "unspecified" error, and Listserv is probably erring on

the side of caution - if the box at the other end is confused regarding

the nature of the error, it may well decide there isn't an error when

you retry. ;)

RFC3463 is pretty specific about 5.1.1 however:



      X.1.1   Bad destination mailbox address



         The mailbox specified in the address does not exist.  For

         Internet mail names, this means the address portion to the left

         of the "@" sign is invalid.  This code is only useful for

         permanent failures.



(Note that your 2 softbounces contain 5.1.1, but in a *later* field.

It's the 5.0.0 that matters....)
