Topic: How Do I Open my SMTP Server to the Public

[Nick]

When I attempt to send a message to an outside email address via my own SMTP server, I recieve the following message:

"The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was (changed@changed.com)'. Subject 'test', Account: '192.168.0.2', Server: '192.168.0.2', Protocol: SMTP, Server Response: '553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79"

I understand that this has been done to protect my server from being used as some twisted dudes mass emailing server, but is there anyway that i could open it up to the outside world? And if so, can i password protect it?

Thankyou, Nick

Dont. Infact.. Please Dont.

see http://www.orbs.org/report_1.html if you do and add your ip there so I wont get spam via your box.

is there no middle ground on this? I would like to be able to send mail from authenticated users, to whomever they choose. I don't want to run a completely insecure server, especially being very new to this. I looked at the ORBS database, and after some reading, I can appreciate the need for security, but am not sure how to balance the two needs.

I had hoped that by using the IMAP function, I could still send email when connected externally. I could imagine adding the required domains manually, but I thank that way would lead to madness....

Any thoughts are appreciated.

You can send email when connected externally. You should just use the SMTP relay of your local ISP, not the (remote) e-smith server. The SMTP relays of ISP are (almost always) open to their own customer base.

I have just found that http://web.infoave.net/~dsill/lwq.pdf contains info on "selective relaying". It would apear that this feature would solve my problem

Your e-smith server is already configured for selective relaying - it only allows relaying for the LAN.

But in reality, you don't have a problem. You already have an SMTP relay that you can use - it is close to you on the Net. It is your ISP's SMTP relay.

Consider an analogy. When you are on vacation and want to send a post card, you put it in the local mailbox wherever you happen to be. You don't send it back to your home address, and then get someone there to post it locally. That wouldn't make sense.

I really like that last analogy Charlie! That hit the nail on the head so to speak.

[Allen]

I like the analogy as well, but I don't think it applies in my circumstances.
I do not plan to have an external SMTP server thru my ISP. My internet connectivity is thru a Fractional T1, and I do not have email services thru this vendor, I only have "connectivity".
I currently have an external mail provider, who hosts my work email, but I want to bring it house to get more control. Unfortunately, that control comes with a learning curve that can't be ignored. I am reading thru the qmail link from Nick, and hope that sheds some more light on the subject.
Thanks for the responses! I am very impressed with the e-smith product, and once I get it configured fully, will probably go with the support option to keep it running nicely.

Thanks again
