mail and newaliases do not work 6.1 and 6.2 for me

Hello misc,

I have strange problem with mail.

I edit /etc/mail/aliases to set well known aliases like:

# Well-known aliases -- these should be filled in!
root:myname@mydomain.net
manager:root
dumper:root

Then I run newaliases but mail is still delivered to local user.

I also run makemap -t aliases /etc/mail/aliases with no effect.

Here is mail log:

May 1 08:31:24 dns12 smtpd[7943]: smtp-in: New session fdcad19418c8f68d
from host dns12.domain.eu [local]

May 1 08:31:24 dns12 smtpd[7943]: delivery: Ok for 4c55f0507959f826:
from=<root@dns12.domain.eu>, to=<root@dns12.domain.eu>, user=myname,
method=mbox, delay=0s, stat=Delivered

It happens on 6.1 and 6.2 but not on all machines I run.

Am I missing something obvious?

Thanks for your help,
Ivo
