SMTP connect() failed

Your MX and SPF are correct for your domain.

If you test email is failing, then one or more of these scenarios is happening:

1. Your host is blocking your access to the Gmail SMTP server. Since your host is GoDaddy, I’m 90% sure this is the case. GoDaddy usually leaves port 443 open, so you could use the Gmail API
2. You are having a password-auth failure. Google may have decided to tighten the security on your account. See https://googleonlinesecurity.blogspot.ca/2014/04/new-security-measures-will-affect-older.html

@charmedlife your site is hosted at GoDaddy.
You have 2 choices to resolve this problem:
1) use Postman SMTP and the Gmail API
2) Remove any and all SMTP plugins since GoDaddy is going to prevent them from working properly.

GoDaddy has a proxy that automatically captures any email handled by PHP mail() and routes it through port 25 to its relay servers. You CANNOT bypass that security measure so disable the SMTP plugin.

If your site owner email address uses the same domain as the website, GoDaddy will send mail to recipients at mulhollandsecurity.com. However, the majority of that email is going to be flagged as spam.

Create a @gateslosangeles.com forwarder using the free pack GoDaddy put in your account. Forward that email address to [email protected]. Use the forwarder for your site owner email and contact form recipient and you’ll get every message.

You’ll need to add an SPF record for gateslosangeles.com that has the GoDaddy SPF include and an IP4 entry for the site’s IP address.

Example SPF for gateslosangeles.com with GoDaddy forwarders:
v=spf1 ip4:160.153.42.70 include:secureserver.net ~all
