I have setup a Website based on HTML with the exception of a contact.php page. I am hosting this website on my Rasberry Pi 3 computer on Debian flavor of linux Jesse Light. This is headless as it hosts my Portfolio website. I am using Apache2 webserver and installed sendmail as my Mail Transfer Agent (MTA). The problem is I have been spinning my wheels researching for the past week and I am stuck.
My issue is I send email from my php contact page on my live server but nothing ever arrives in my inbox after sending it. I get a mail sent message from my php script after about a minute after sending but then Nothing arrives in the inbox. I am thinking My SMTP on my php.ini is not correct. I put my website domain name FQ name. I am using Microsoft Exchange Online hosted email domain by GoDaddy. Also, anyone have any good advise on what my from / to should be set to on my SMTP configurations?phphtml5apachedebian-jessiemail-sender
Sounds like a direct reject to me.
Hope that helps. Otherwise please provide more details and log samples.
Is your contact.php program hosted on the Godaddy server? If yes- It's not possible to send mail through Godaddy shared hosting servers using your own SMTP settings. You can only send from Godaddy's relay server when using a shared hosting plan. If you wanted to be able to send through your own SMTP servers, you'd need to be hosting with either a VPS or Dedicated Server plan.
Check maillog on your server and you will get the smtp connection timeout errors.
Let me know, in case the problem is something different- will try to address it.
