I am working with a client to provide a new website. this will change the hosting to my virtual servers (under 1and1).
In repointing the DNS settings to my server from their existing domain (under demon.net) I also need to ensure that their email will still work.
My client uses MS exchange for mail, so in repointing I have ensured that for the mail servers I have repointed them to the existing settings:
(My IT support say that MS exchange is hosted on the clients server within their office)
Realising, from the settings above, that there is a new sub domain "mailgate.MyClientsDomain.
com" I have now set this up on my hosting package.
However my IT support has said that they cannot access http://mailgate.MyClientsDomain.com/exchange/
I have found a bit of supporting information from demon.net
it says that the IP for mailgate.MyClientsDomain.c
om needs to be pointed to 192.0.2.0 . So I have tried to make these changes on the DNS setting within the 1and1 account, but I get a message that this IP address is not valid.
The Demon Knowledgebase also mentions another subdomian mail.yourdomain.co.uk.
Any suggestions on what I have to do to get the mail working here.
