Getting sendmail to install/work for using php mail()
- by harryg
I'm running WordPress on a Ubuntu VPS. When WordPress tries to send an email like a password reset or registration email it never gets delivered. WordPress uses php's mail() function.
I figure it's not working as my VPS didn't have sendmail installed. So I went into SSH and installed it with sudo apt-get install sendmail which appeared to succeed.
Following more googled advice I edited the php.ini file to have the sendmail path.
I located it as being /usr/sbin/sendmail which I believe is typical for many *nix servers. To check I browsed to this directory on FTP. The "sendmail" directory appears to be a shortcut. Is this correct/expected?
Either way the php mail function is not working. I have created a phpinfo file and a test mail php file which contains just a mail() function with my email as the recipient.
Note: my VPS doesn't yet have a domain, just an IP address. Would this affect sendmail functionality?
My phpinfo is here for your reference: http://95.142.166.209/phpinfo.php
Do I also need postfix? I don't think I have it...
Here is some of the mail log. I executed the mail function towards the end:
