Topic: SME SMTP Server with dynamic IP?

[nichterwitz]

Hello,

is there any solution out there for using my providers SMTP Server to send my Email through it?
I cannot give any login information in the email settings but the relay server from my provider requiers an authentification and when i directly send emails out from the server the most providers don't accept my emails.

Hope you can help me.

Depending on your SME version, you will have to use your provider's auth on each client (which means you'll have to disable SMTP proxy).
On 7 this has been added, and on 6.5 read this thread:

Hth,

But is not a SMPT proxy and a SMPT server two different things ?

If you are using the Qmail mail server of the SME server you should not need to access your ISP SMPT server at all ??

I have used a dynamic ip ADSL connection (with sme server) for 3 years now. I think I have never asked for or configured up to my ISP SMPT server.

I think all mail is sendt directly from my lacal mai server to the mail receivers mail server so there is no need to log on or access my ISP mail server (SMPT) at all.

To check out if the local mail server works and if it has free access to internet:

Activate Horde web mail and send out a mail to your hotmail or gmail acount. When it is received, sent it in return.

(Of cource you will have to had set up a correct external dns entry if this should work.)

Don't know if it is something with the question I don't understand. No need to use  "my providers SMTP Server to send my Email through it"

It should be just to bypass it all ??

(Unless you want to use your internet providers SMPT and not your own. In this case I believe login info (for sending mail) will have to be configured on each client.)

Well, sending mail directly from your server is a _bad_ idea if you have a dynamic ip address..

most of the BL services put dynamic subnets of ISP directly in black list..

just my 2€c

"Well, sending mail directly from your server is a _bad_ idea if you have a dynamic ip address.. "

In theory yes. In the practical life not neccessarely.

During the 3 years I have used mail server with a dynamic ip there have never been a problem with mail that have ben lost or that have been rejected.

It is true that some theory says that mail servers on a dynamic ip are blaclisted, but in real life it have worked so far without a problem. (Hotmail, Gmail, Yahoo and all those "big" comunicates without a problem.

Dont know if some dynamic ip's can be more blacklisted than other but for me it has not been a problem. As far as I know 0 mail have got lost during a period of 3 years.

"Dynamic Ip" might also be a relatively term. My "dynamic ip" changes in the real life something like every 3 or 6 monts, with 24 hors logon, so it has technically and practically not been a problem at all.

I agree with nenonano,

sending mail directly from your server is a _bad_ idea if you have a dynamic IP address

For example, recently I used comcast (cable provider)as my ISP and had a very difficult time sending mail.

Two things happened.
1. Some servers recognized I was sending from a dynamic IP and rejected the email.  Most accepted it fine, but a few rejected the email.

2. All email sent to another comcast member was rejected by the comcast servers.  Their mail servers new I was sending from one of their IP's and also new my server was not one of their SMTP servers.

The problem for me was that I could not know for sure the messages would be delivered.  Without that sense of reliability, I had to stop using my own mail server.

To resolve this problem, I installed several contribs from this web page:http://no.longer.valid/phpwiki/index.php/SME6.0.1Contribs

The FetchMail contrib has the option to disable the SME server's SMTP proxy, allowing my email client on the individual workstations to send directly to my ISP's SMTP server.

Although I have not tested any other features of this FetchMail contrib, the ability to turn off the SMTP Proxy solved my issue perfectly (running sme 6.0.1-01).

I have tried the SMTP Patch but it seems not to work. The current Log file from qmail tells me that the server requieres authentification.
In the smtproutes there is my IPSs mailserver and username and password Base64 encoded.

For now i disabled the SMTP proxy but thats not a good solution.

But thanks for the hints.
