Sendmail Error

[tenera]

Sendmail is not working for me (for any emails sent by the forum). After some searching, I found a few threads that gave me some leads, but none of them worked out. Here is the error that was logged under the IP Error Logging:

Ran into problems sending Mail. Error: 530 5.7.0 Must issue a STARTTLS command first

php.ini is pointing to the correct location for sendmail. Any ideas what I would need to do to fix this? Thanks in advance

Does sending mail work just through PHP?  You can test it with a simple script like this:

<?php

mail('[email protected]', 'How goes it?', 'Just wanted to know how you\'ve been.  I\'m just worried because I heard I was talking to myself by email - what do you think, self?  Am I crazy?');

?>

SMF doesn't support TLS with its SMTP support, but PHP might.  I'm not sure.  Do you have the possibility of using any less restricted SMTP server?

Check your mail prefs in "Edit Features and Options" what's it set to? Sendmail or SMTP?

I tried the script, and the email never arrived. As for the TLS error, I guess that's from when I tried using SMTP instead of sendmail. I realized SMTP would not be an option, as the SMTP server requires SSL and SPA, so I set it back to sendmail after then. My sendmail settings in php.ini are the default ones (sendmail -t -i), so it should work. I guess it's a matter of sendmail not being set up correctly on the server? Also, I know the email address sendmail would tell it is being sent from is not a valid email address (does that matter?).

It may.  Many smtp servers will do a reverse dns check on reciept and bounce the email.
