Sendmail Query - PHP script

[tech_paul]

Hi,

Scenario:

I have 2 servers, 1 webserver (incl. dns) and 1 mail server in the same network. In the webserver there is a PHP script that is sending e-mails (to an account on the mail server) but is sending them locally on the webserver and not to the mailbox on the mail server. The webserver is like, it does not know that it should NOT handle emails for that domain, but route it to the mail server (where the mailbox is).

If I set an external account (gmail etc..) that is not hosted on the webserver, it works fine. The problem is when I set the php script to send to an account from my mail server.

What can I set on the web server in order to route emails to the mail server please? Can this problem be solved please?

ANY HELP APPRECIATED!! Thanks in advanced

mx record, local domains, etc. will depend on what SMTP server you have on the webserver...

[tech_paul]

Can you please elaborate what I need to do? I have mx records on the webserver that eventually they point to the mail server.

What do you mean by "depend on what SMTP server"? I have sendmail as an SMTP server.

Thanks for your reply

There may be something in the sendmail config on the webserver that tells it to deliver mail for your domain to users on that host, as opposed to sending it out to your real mail server...

Thanks very much for your reply.

I have tried to set it as you told me but than no emails can be sent! Do I need to setup something on the mail server to accept the webserver to use its smtp pls?

What's the output of ls -la /etc/mail/?

[tech_paul]

Hi Falko,

Please find the command ls -la /etc/mail on the webserver:

Do you need the result of this command on the mail server?

Is the domain listed in /etc/mail/local-host-names? If so, remove it and restart Sendmail.

[tech_paul]

Hi Folko,

That file is empty so there are no domains in this file. I have read something that I need to do the sendmail on the webserver to relay through the sendmail on the mail server.

Have you ever done this please? Or do you have any other suggestions?

Thanks for your help

Paul

[falko]

I've done this with Postfix, but not Sendmail...

[tech_paul]

Hi Folko,

If you can tell me which main parts I need to configuring on postfix and how, maybe I can adopt it to sendmail. I will try to find similar config. I believe they are very similar right?

Paul

[falko]

No, unfortunately you can't compare Sendmail and Postfix configuration - they are very different (and Sendmail is a nightmare to configure...).
