Exchange receive connector query

Hi folks. I am migrating mail for a small company from hosted pop accounts to their own new internal Exchange 2010 box.

Their mail accounts are in the format user@companyname.com. Their domain (for some reason known only to whoever configured it whos long gone) has a sub domain so its abc.companyname.com. As they of course want to keep the same email addresses I have configured the email address policy to match the existing format, so far so good.

Their ISP is making the MX change this evening for me to point to mail.companyname.com and their public IP here (router is configured)

I have configured a send connector to sned mail out via their broadband providers smtp server which authenticates via their IP so I'm not anticipating any issues here.

What I am wondering about though is the receive connector, Its currently: SvrExch01.abc.companyname.com

Can I just leave this as is? Does it need to match the FQDN I have in the send connector which I have set to:  mail.companyname.com

Thanks for the help.

The recieve connector generally will have the fully qualified server name not domain name.

OK cool thanks, just wanted to confirm as much. I have set the FQDN on the send connector to mail.companyname.com, correct or should that also be left as FQDN of server?
Nope, the send connector has to be the FQDN for which you are sending email.
Just to clarify, so I don't cause confussion you have the send connector setup properly. I was say nope to the fully quallified server name.

OK thats fine I have ya, thanks again
no problem, just an FYI you have the option to create Internet only facing recieve connectors that can be setup using the FQDN, but your default connectors need to use the server name.

Ok, any advantage or reason in a small deployment like this or will I leave it as is with the defaults?

And oh ya, on a side issue, if the hosting company changes the MX at 9PM tonight, it should be propagated out by morning yes?
In a small deployment the defaults are usually fine, you just have to have one recieve connector that has anonymous users checked under permission groups or you will not recieve external email.

Generally yes you would be set by morning if the record is changed at 9pm, though I have see it take up to 24 hours... its more common however to be reflected within a couple of hours.

Ok, the permissions I havent touched and the default doesnt allow annoymous connections. Whats the difference between the client and default and on which do I enable annoymous?

Also, i noticed it using port 587, assumed it would be 25? I have forwarded router for 25..

ok, digging a little deeper its the default I need to set anonymous on yes? That doesnt open up the server as an Open Relay does it?
Okay, "Client" should be set up to use port 587, that's for internal users so they can access the server via Outlook, it can also be used for the users to access via POP3 in teh event that you install a spam filter and need another port available for access. "Default" should be set up using port 25 and should have the anonymous option checked. This does not allow open relay, this simply allows outside servers to connect to your exchange server for the purposes of delivering email.
