Setting basic smtp server for one website

Hi,
I would like to set up a custom smtp server for the php mail() function only for one website. I've tried to add those lines into "Custom php.ini directives";

Code:

SMTP="mail.smtp2go.com"
smtp_port="2525"

When I run phpinfo(), I see that the values have changed. I then ran the script to send the email and I received it. BUT, when I check the headers of the email, its still sent by local postfix and not from the custom SMTP specified in php.ini. Am I doing something wrong?
Thank you very much for your help

 

Im using a plugin for all our CMS/WordPress websites that allow me to send trough SMTP like you mentionned, so I never had the problem before. In this case, its a custom made website that use the really basic php mail() function and I have to find a way to send these emails using their smtp2go account. Is there something that I can do?

 

Thanks for your replies till, it helps a lot.
Do you think that will cause problems with future updates? If I understand, I can install this "sendmail copy" with smtp support and only use it for this website by configuring the sendmail_path into the custom php.ini directives. I do not want to replace the "real" sendmail in the default php.ini so that other websites are not affected right?

 

Hi till,

I tested it right away. But it seems that the sendmail_path value does not want to change.
I entered into custom php.ini settings, is that what you meant by php.ini field of the website?

Code:

sendmail_path = "/etc/sendmail-smtp/sendmail.phar -f /etc/sendmail-smtp/smtp2go.yml"

I checked with phpinfo() and it returns the default value which is

Code:

/usr/sbin/sendmail -t -i -f [email protected]

Do you know why it does not change?

 

I am on Fast-CGI PHP 5.6, it is default setting in my case. I tried with PHP-FPM too, but no luck. If necessary, I can switch to another mode. I took my time to search in the forums and it seems to be an hard one to change. The only thing I found is parameters in a file named .php-fcgi-starter. Maybe you have the trick to do it.
