Sending mails via PHP (SSL)

December 8, 2014 1.2k views

Hey guys.

I configured my mail server as in the following guide:
Now I am trying to send mails via PHP using this library:

But the problem seems the SSL (cert). I am not sure if the script is not able to establish a connection or if the problem is the unverified SSL cert.
Do you guys have any idea?
Should I use startssl oder starttsl in the script?

Thanks in advance

  • You should debug your script for errors. Or another problem can be a misconfiguration if you didn't follow the tutorial through.
    Anyway, i have a mail server with Postfix, Dovecot, SpamAssasin and i configured it successfully by following this article.

  • So I've never debugged my scripts before.
    Do you have any link or tutorial for me?

    Thanks in advance
