Configuring exchange - port forwards
-
What happens when you telnet from your exchange server to the mail server on port 587?
Note that outbound connections such as sending mail don't require a port forward. They only need outbound NAT (if NAT is necessary).
-
As when I used hmail server I could send and receive on port 587 SMTP so I really don't understand why exchange wont send out using port 587 as hmail worked perfectly using that port
If you are saying you could send mail to arbitrary mail servers on 587, things weren't working like you think they were. Most mail servers on the internet require authentication before you can send ANY mail through them - even to the local domains they serve.

when i have my exchange server on at home, from work i can telnet in on port 587 (my new SMTP send connector) and i get a reply back (220 mail server ready at your service) but when i had my exchange using port 25 (SMTP send connector) i didn't get a response so i can safely say virgin media block port 25 for outgoing emails
i can receive emails when i make my send connector SMTP port 25 but when i make it port 587 i cant even receive nor even send but i can telnet into it which i dont understand atall
-
I'm going to have to step back and let you decide what ports you want open from where to where. When you figure that out, I'll be happy to help you get pfSense doing the right thing.
-
thank you Derelict,
i do want to make my SMTP send connector port 587 as virgin media block outbound port 25
-
Then do that. It should require no configuration in pfSense. I can't help you with configuring exchange. exim/sendmail/postfix maybe, but not exchange. good luck.

thank you, you have been very helpful

as virgin media block outbound port 25
Hi,
Sorry for maybe putting the cat amongst the pigeons but I am on virginmedia cable and they do not block port 25, I have my test exchange 2010 box running fine with minimal configuration and on port 25
-
mmm…
reason why i am asking if 25 is blocked if i run a telnet command from the internet i cant connect to my mail server using 25 but i can when i change it to 587, it says 220 my mail server is ready
obviously i port forward the correct ports 25/587 to my exchange server at the time im testing the above command
as every time i make my send connector 25 i cant send but i can receive, guess i will try with exchange 2010

But what you're saying is contradictory. If you change to port 25 and "can receive" that means other mail servers can make the connection to you on 25. Which is the opposite of your telnet test experience.

Hi all
Good news its working, i will quickly describe what i did
I found out one of the services "MS EXCH Mailbox Transport Submission" wasnt running when i listed in order of automatic services
I made my send connector back in using port 25 instead of 587 as mails would not send
Once i did that my messages went one by one to my sent items in OWA and i had about 23 emails in my gmail inbox
Also i did this -

I added for internal dns my domain controller ip and in external dns my isp's dns and google's dns
