Mail-Address with captial Letters after Upd. 9.06->10.20

[Michael Starogardzki_1]

Some days ago I updated from 9.06 (via 10.01) to 10.20.

Since then, one user could not receive e-Mails any more. Narmally her receives
e-mail notifications from an over night backup task.

When directly mailing with mailx (by hand) I got the message, that the user
does not exist.

The only difference to other users is, that the user-id starts with a capital
letter.

I created two new users to check it. One with the name test and another with
the name Test. The first receives mails, the second does not!

Is it a feature or a bug?

I did not find this subject in the update-docs - sorry

Regards Mike

Yes this is a bit strange you will find that for all purposes the accounts are
seperate. i.e bob and Bob can exist on HP-UX as seperate accounts but when you
use things like mailx all mail sent to Bob will end up in /var/mail/bob I think
this is a Sendmail thing rather than a mailx/elm/mail issue. As a general rule
most admins stick to lowercase login names as well as unique ones.
