Sending Mail from home

[A15]

Hi
We have an NT4 SP6 and exchange 5.5 SP4 running in the company.
I have tried setting up my home outlook express to send and receive e-mail through our exchange server.
The problem is that I can receive e-mails but unable to send.
Is there any way that I can configure my exchange server that will allow me to send from outside my office network.

I already have ports 25 and 110 open.

Thank you

A15,

Contact your ISP to see if they block outbound 25 EXCEPT to their email server...that'll be the problem.

You could do a quick test from home. Try to:

TELNET MAIL.YOURCOMPANY.COM 25
^You'll have to find out what this is.

If you cannot connect then it's your ISP causing the problem.

Also, if the ports 25 and 110 are open on your home router, close them...they only need to be open on your business's router.

Another suggestion. VPN. Use Outlook 2000 (not Express) in Workgroup mode through a VPN tunnel. That works best, too, because your email will stay on the Exchange server.

Thanks for the response.
I am not a telnet user but I was able to connect, I got my servers name at my ISP Network.
However the error message that I get when I try to send out is:

"Server response: 550 relaying is prohibited. Port 25 secure (SSL) No, Server Error 550 Error number 0x800CCC79"

Any Idea??

This KB article has that error in it. Might explain the problem:

The good side of this is that it shows your setup is working to prevent your company being spammed. They can't relay through your server and leave people thinking that you are doing it.

On the flip side, there is a work-around for this. Simply set your email to send outbound mail via your home server and bring in your work email via your work server. Just change the account and all works great.

The downside is people will learn your home email address and you may not want that. This will, at least, give you the ability to send replies.

one thing you need to check is whether your nt account assigned to the mailbox is the same as your alias name. so if you nt account is joe.blow your alias has to be the same or you will not be able to recieve mail. however, this assumes you are using a pop account.I use eudora at home because its so easy to set up.

Any reason why OWA (Outlook Web Access) wouldn't work for you?

OWA for exchange 5.5 is very laime.....and most of my yousers like to work with outlook....
I have also checked whit my ISP and he has ports 25 and 110 open, I guss it has something to do with relaying so I rather have a secure server and not allow users to log with outlook than having an unsecure server and dealing with black holes NDR's etc.....
