Sendmail directories... /var/state/sendmail...

["Ian Perry" <iperry@inertia.com.au>]

Hi,

I have noticed some wierd directories on one of our mail servers, and so I
checked the others.  hey are on all of them in some varying degree or
another.

/var/state/sendmail....
then ae. at. au. etc

then in au.
asn. com. edu. gov.

then in com.
aapt. acay.

then in acay.
job which contains
V0
E29
H1
S0
D2.0.0
R250 QAA13472 Message accepted for delivery
U975647737
.

I can see that these are in reverse order... such as acay.com.au

Is this a quick DNS lookup or what purpose do they serve ?

Many Thanks

Ian
