Use smtp for test email even if module not "on"

That's true, Drupal can send email without any modules.

But I have a reasonable question:

"What smtp-server does it use???"

I notice there is no settings in Drupal to put login and password for smtp authentication. How does it work then?

Does anybody know?

kogor:

Drupal's default mail system uses PHP mail system, so whatever is configured on it will be used. This usually corresponds to the machine's mail sending mechanism. On unix-based systems, it uses the /usr/bin/sendmail command. Well, the machine's mail system might be configured in a whole number of ways, and may be wrongly set or such. On my machine, I even configured the system to use Gmail SMTP server. That's why this module exists, so you don't have to configure the server (to which you won't have access most of the time).

As to the issue, I changed to user interface.

By the way, I was thinking of just disabling the testing field when the module is off and displaying a message next to it explaining. That will be a quick fix. I'm a new maitainer, so I don't really know all the bits of code to say whether is possible to send a test e-mail WITH smtp settings while it's OFF.

franz,

Is there any possibility to pass around the machine's mail system? My hosting provider closed the necessary ports for outgoing connections to external smtp-servers (such as smtp.gmail.com). They force me to pay them much money for this opportunity.

Can smtp module help me?

Mmm, I've never tried anything like that. You would need to have a proxy to fool yor webserver. Or maybe a SSH tunnel, if you have SSH access to somewhere else (but it might be closed as well).

If you manage to use a proxy for a connection, I'm still not sure if phpmailer supports that.

Closing very old (dead) issues, if you think this is still relevant please re-open.

The Issue still exists, and i just ran into it too.
(This is a great module, and i hope my feedback might help the next new user to get into it quicker.)

Only when i looked at the mail headers i realized what was happening.

I think a better help-text as in the issue summary would be an easy first fix, before more work is done.
(It should also state the fact that this will send a test-message upon saving this settings page.):
Instead of

Type in an address to have a test e-mail sent there.

I'd suggest

Type in an address to have a test e-mail sent upon saving this form.
WARNING: Mail will be sent via the default mail system until the module's functionality is enabled
(first option on this page, it must be saved first, before it affects the test mail.)

First i thought the behaviour should be to only send via SMTP Module, or do not send and show a message.
But in some scenarios it might be helpful to be able to send a test mail with the default mail system too, to compare things.
So i would maybe suggest to add a line to the test-mail itself,
"Sent via SMTP Module" | "Sent via default Mail System"
"See mail headers for more details"

Ideally, the test mail should be sent via SMTP already if the module is being activated in the same step.
PS:
This setting, "Turn this module on or off" is also confusing in itself, at first it seems to double the setting on the modules page, i created a separate issue about that: #2741675: Ambiguous option "Turn this module on or off"

Just noticed the Test-mail content:

If you receive this message it means your site is capable of using SMTP to
send e-mail.

This clearly indicates that the programmer wanted a mail that goes through SMTP in whatever case...

@sirtet please update the target version for the one where you are experiencing it.
