[LUG] Postfix emails to smmsp and root?

[Gibbs <linux@xxxxxxxxxxxxxxx>]

I'm getting quite a few of these in my mail and system log from Postfix. 
I was just wondering if it's anything I should be worried about?

Also, whilst Im on the subject, is this setup correctly (I dont seem to 
be having any problems but the loopback got me thinking):

myhostname = mail.mydomain.co.uk

mydomain = mydomain.co.uk

mydestination = mydomain.co.uk



Finally I've also noticed some access denied requests. After a quick 
Google it seems they're trying to use my mailserver, amazing since it's 
only been up a day on a new domain and IP!

Feb  7 16:11:39 srv postfix/smtpd[5970]: NOQUEUE: reject: RCPT from 
118-167-7-34.dynamic.hinet.net[118.167.7.34]: 554 5.7.1<superedm001@xxxxxxxxxxxx>: Relay access 
denied; from=<8888@xxxxxxx>  to=<superedm001@xxxxxxxxxxxx>  proto=SMTP helo=<87.239.22.114>


Cheers,

Gibbs
