Hey all, really having a hard time figuring out what the hell is going on here.
I have setup my droplet to send emails through an SMTP server that is running microsoft exchange.
I have a PHP script that will send an email using mail() and it works fine if I open that script in a browser.
The problem arises when I set up a cron job to trigger that script. Then it doesn’t send.
And worse yet, it doesn’t send to only certain email addresses.
Once again, if I open the same file in a browser, it works fine.
To troubleshoot, I’ve removed everything in the php script except for the mail() line. It still has the same issue.
When I check the mail log, this is what I get:
Feb 20 01:11:32 <my hostname> sm-mta[17139]: s1JNS1Rl014657: to=<Email I’m Sending To>, delay=01:43:31, xdelay=00:00:00, mailer=esmtp, pri=840740, relay=ms15341115.msv1.invalid.outlook.com., dsn=4.0.0, stat=Deferred: Connection timed out with ms15341115.msv1.invalid.outlook.com.
Any ideas on where to go next?
