I'm confused about relaying on virtual servers and smtp connectors.
I keep reading conflicting reports-
In "Microsoft Exchange Server 2003 24seven" from Sybex, JMcBee writes in chapter 14 on page 584 that unchecking "Allow All Computers WHich Sucessfully Authenticate To Relay..", Exchange servers will not be able to send mail to one another.
He states Exchange servers relay with each other in an Org all the time and unchecking this will break exchange.
Jim McBee has stated this in both Exchange 2k and 2k3 verisons of the book.
However in "Exchange Server Cookbook", recipe 7.19, they state to uncheck this value for security reasons and seem to imply that this is only for pop3/imap clients.
Tony redmond in "MS Exchange Server 2003 with sp1" seems to agree as well.
who's right?
Also, I know the setting for relaying on an smtp connector over rides the virtual server connection setting, so say i create a connector with "acme.com" address space. If i uncheck the relay button on the connector, will users(mapi or pop3) be able to send mail to
acme.com?
or do i have to enable relaying for this to work on that connector?
Finally, how does exchange view mapi users?
are they lumped in with auth users like pop3/imap?
what mechanism allows mapi users to relay? is there a setting that can disallow mapi clients from relaying like for pop3/imap clients?
Thanks.
alot of questions, i know.
Exchange in some ways confuses the heck outta me.
I find the sendmail.cf file easier than exchange sometimes.
Thanks again!
