I am having a few issues with email.
Some users have reported that they are not getting emails that they know have been sent. the user sending is not getting a bounce back .
The second and more important issue is when sending some emails, the users are getting bounce back
We are using exchange 2003 and normally go outbound via a smarthost (BT) but due to some issues which Bt are fixing I have switch to use DNS for outbound emails.
as we don't normally use DNS i have not setup a reserve DNS lookup but will look at tonight.
Can some body explain exactly what steps need to be done to correctly setup
We have a MX record setup, As far as i know this is all that is needed for incoming email
Using BT Smart Host
As far as i know i don need to setup anything as BT take care of all that
Setup RDNS which matches my Mx record
DO i need a SPF record setup at the domain level (this is an issue if i do as where the domain is hosted you cant set one up as it a shared hosting package with 1and 1.co.uk
All there anything extra i need to setup in exchange ?
What is this mailreport.co.uk ?
I have also noticed we keep intermittently being found on 1 blacklist site. the site is MAILSPIKE-BL. It only shows up on mxtoolbox and not any others i have tried and removes it self within a short period of time
