sendmail or postfix?

Does dolphin use sendmail or postfix? And if it can use both, how does it know which one to pick? Is there a setting somewhere that i must set

OS: OpenSuSE 11.1

Webservice: Apache2

PHP Version: 5

MySQL: 5.0

Dolphin does not use either.

Mail is sent using PHP functions. So whatever PHP is setup to use, it what is used.

Does that mean I have to tell PHP what to use? or is it automatic? Basically i cannot get email notifications to work. It says the email was sent but i never receives anything.

How do I verify that the php mail functions are working correctly?

You should not have to do that. The install of one of the mail servers should make those adjustments.

Those settings are in your php.in file.

I'm having the same problem all of my settings are correct but i'm unable to send nor receive any messages from the admin control

Awesome. So php.ini is the one I must edit.

Can you show me an example of what is supposed to go there for the mail functions to work?

Well as i said, you should not have to touch those settings.

[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25

; For Win32 only.
;sendmail_from = me@example.com

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /usr/sbin/sendmail -t -i

These are the defaults if sendmail is installed. I don't use postfix, so i do not know, but you should not have to touch these.

This is really a hosting issue.

As long as your email addresses in dolphin are setup with valid email addresses then it should work. If it don't then it's a hosting mail server issue.

Now are you running your own server, or hosting with someone else?

If hosting yourself then you should be looking at your mail server setup.

I guess i need to know your current hosting situation first before i can make any suggestions.

Yes, I host my own mail server. I am using a program called Mail Enable that runs on top of a separate box running Windows Server 2003.

Question though.....

I know you said I should check my mail server's configuration......But you did say that php.ini may require "sendmail_path = /usr/sbin/sendmail -t -i" ............assuming that sendmail is installed.

Now if sendmail is installed by default, is there any configuration needed on the sendmail side to get "sendmail_path = /usr/sbin/sendmail -t -i" to work?

Like do I somehow need to tell sendmail my mail server's IP/authentication information?

I am not familier with Mail Enable.

But i do have another question.

Does your server send mail directly, or do you need to relay your mail through a smarthost. Like your ISP's mail server.

Also is a firewall involved. If so, is port 25 open?

Reason i ask the first question is becuse you said. "Like do I somehow need to tell sendmail my mail server's IP/authentication information?"

That suggests to me that you do need to send out through a smtp smarthost. In that case, then yes, sendmail needs to be told what server to send the mail to, and any auth information it needs.

Nah. I don't have a smarthost. I actually host my own smtp and pop3.

What I was wondering was........Since php.ini may require "sendmail_path = /usr/sbin/sendmail -t -i" if sendmail is installed, is there anything needed to be configured in sendmail as far as my mail server's IP address and authentication information is concerned?
