[NTLUG:Discuss] Sendmail giving me user unknown for a local user account

- I do have parasailworkshop.com in my local-host-names file.

- As a test, I created another user account with the name
- parasail and changed my mapping to point to that
- and everything worked fine.

- So, any ideas why sendmail would accept "parasail"
- but not "parasailWorkshop"?

	Mixed case user names.  By default, the mailer
definition for Mlocal mashes case.  So you've got a user named
parasailWorkshop, but sendmail is looking up parasailworkshop,
and missing.

- Is this a bug in sendmail?

	No, it's a configuration issue.

	Generally, most sites want all users names mashed in
case, so things addressed to Neil, neil, NeIl, etc end up in
`neil's mail box.  

	Strictly speaking, the left side of an email address is
host dependant.  Hoever, most people _assume_ that it is case
in-sensitive, just like the right side of an email address.
(read RFC 822 and successors/amendments for more details.)
