Gatt Posted July 30, 2009 Posted July 30, 2009 Can receive external email, but cannot send - have set up a Send connector and it is pointing to our Smart Host... Also got a prob with OWA and ISA using an SSL externally but thats on hold until I can get a bnew CNAME created by our DNS Providers...
EduTech Posted July 30, 2009 Posted July 30, 2009 have you setup the rule on your ISA box? Protocols: NNTP / NNTPS / SMTP Server / SMTP From: Internal / Local Host / (COMPUTER) < You might need to add this if you havent already done so To: yoursmarthostaddress ALLOW ?? James.

Good point - will check it, though think its already there!
IanT Posted July 31, 2009 Posted July 31, 2009 silly thought but is the router configured properly to forward? do you get any NDR's?
FN-GM Posted July 31, 2009 Posted July 31, 2009 silly thought but is the router configured properly to forward? do you get any NDR's? For outgoing it shouldn't need to. Is port 25 blocked going outwards?
Gatt Posted July 31, 2009 Author Posted July 31, 2009 No, its open... Not had any NDRs yet - just "Delayed" reports... Seems odd that i can receive but not send - usually its the other way round!
Gatt Posted July 31, 2009 Author Posted July 31, 2009 Right, This is what I need to work on over the weekend Checked the Message Queue in EMS and seen this: 451 4.4.0 Primary target IP address responded with: "." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. I can find no reference to "." however... At home as caretaker chucked us all out and sodding VPN still isn't working
Oops_my_bad Posted July 31, 2009 Posted July 31, 2009 Where abouts is your smarthost located in relation to your exchange server? One good test - see if you can telnet to your smarthost (on port 25) from your exchange box. You may also get a more meaningful error message!
IanT Posted July 31, 2009 Posted July 31, 2009 For outgoing it shouldn't need to. Is port 25 blocked going outwards? I know sorry, My fault wasn't thinking at the time

You may also get a more meaningful error message! smarthost is external - cannot telnet to it.. ot sure if thats me or them though....
Oops_my_bad Posted July 31, 2009 Posted July 31, 2009 smarthost is external - cannot telnet to it.. ot sure if thats me or them though.... Make sure you are specifying port 25 as the port - telnet will just default to 23 otherwise
Gatt Posted July 31, 2009 Author Posted July 31, 2009 Will do Weird thing is that it was working on my previous setup albeit on Exchange 2003! Guessing my ISA is a bit pear shaped as cannot get my VPN working either! I can get out but nothing can in!!
Gatt Posted July 31, 2009 Author Posted July 31, 2009 It's beginning to look that way.. What are the benefits for having an Edge Server and where is best to put it? (in or out of the domain?)
DrPerceptron Posted July 31, 2009 Posted July 31, 2009 You aren't still running an Exchange 2003 server in parallel are you? That bugged me for a few weeks when I added Ex2k7 and Edge to the list. Edge server's are handy, basically they sit at the Edge (shock horror!) and filter all the crap before it reaches anyone's mailbox, we're using one here and it's very swish, it doesn't add any overhead to the other boxes handling mail rules it does other things obviously, transport rules etc, but we're using it as a spam filter ultimately. Quite a few of Microsoft's products now come with an Edge functionality, OCS being the other I can think of immediately. 1
Gatt Posted July 31, 2009 Author Posted July 31, 2009 No its a brand new network & domain - no trace of E2k3 anywhere Think I'm gonna rebuild the ISA server on Monday and see if that helps...
DrPerceptron Posted July 31, 2009 Posted July 31, 2009 Always worth checking, your Anti-Virus isn't blocking the Transport service/executables is it? I took teh software firewall and AV out of the equation completely while I feebly attempted to understand the complexities of Exchange. Being able to connect to your smart host from either any PC in the domain or your ISA/Exchange box is a given... It'd be worth verifying your Send Connector is setup correctly and if you think it is, start playing with it until the b~%&$£d works! I believe, I can't remember, that our Send Connector provides our Smart Host in response to HELO/EHLO as well being listed as "route through the following smart host" option... On a side note: mmmmmm Jaffa Cakes.
EduTech Posted July 31, 2009 Posted July 31, 2009 I must admit i had a few problems with ISA 2006 to start with but got their in the end. @ GATT if you want i will send you over a copy of our config and you can take a look at that it might help you solve the problem. our setup is also through a smarthost James. 1
EduTech Posted July 31, 2009 Posted July 31, 2009 No Prob, If i can get it tonight or over the weekend i will depending on how my VPN copes if not i'll email them first thing monday morning. James. 1
DMcCoy Posted July 31, 2009 Posted July 31, 2009 It's not like your smoothwall box is it with int/ext being the same subnet? as it will think that the server it's trying to contact is in it's local subnet and not use the router.
Gatt Posted July 31, 2009 Author Posted July 31, 2009 erm - not sure - though the ext NIC is "outside" ISA's range
Gatt Posted August 3, 2009 Author Posted August 3, 2009 Always worth checking, your Anti-Virus isn't blocking the Transport service/executables is it? You're a genius!! now to get the OWA and VPN working....think they are related as its login related..
DrPerceptron Posted August 4, 2009 Posted August 4, 2009 A genius? or some guy who suffered the same mistake.....twice!
