simm Posted March 25, 2009 Share Posted March 25, 2009 Hi all...I'm new here - don't know if this is the right place for my question. I get a 503 SMTP error when I try to send an email from a simple form on my local Vista machine. I've tried an email address from my own domain, gmail, hotmail, and yahoo. Here's the error: Warning: mail() [function.mail]: SMTP server response: 530 5.7.0 Must issue a STARTTLS command first. k14sm6838908waf.23 What's the deal? I'm going through a PHP book, and it doesn't cover any error troubleshooting. I've tried everything it seems - from IIS settings to SMTP settings on my local machine to the PHP.ini. Thanks so much.

trq Posted March 25, 2009 Share Posted March 25, 2009 Are you using a local mail server? Quote Link to comment Share on other sites More sharing options...
PFMaBiSmAd Posted March 25, 2009 Share Posted March 25, 2009 The php openssl extension must be enabled/installed for php to be able to connect to a mail server using TLS/SSL. Quote Link to comment Share on other sites More sharing options...
simm Posted March 25, 2009 Author Share Posted March 25, 2009 Are you using a local mail server? Yes, I believe so. The php openssl extension must be enabled/installed for php to be able to connect to a mail server using TLS/SSL. I tried enabling openssl, but it's still not working. Thank you for your replies...please keep asking questions, as I'm very new to PHP and I don't know a ton about it... Quote Link to comment Share on other sites More sharing options...
