   1.  Is there any "standard" (as defined by RFC or otherwise) as to what the
   "proper" eol is for an IPC mailer?

RFC821, section 4.1.1, page 19:

|       4.1.1.  COMMAND SEMANTICS
| 
|          The SMTP commands define the mail transfer or the mail system
|          function requested by the user.  SMTP commands are character
|          strings terminated by <CRLF>.

In other words, "E=\r\n" should always be set.  There's no reason ever
to use just "E=\n."

   2.  If "\n" is proper, will other mailers COMPLAIN about the extra 
   <return>?  Will addresses, for example, get misinterpreted if there is an
   extra "carriage return" on the end?

No.  And in fact there are other systems which demand strict
compliance with this section, such as DEC-20s running MAISER.
