SMTP Email Not Working

Garrettj94

• October 07, 2015 22:44

To start off, I am using the FormCraft WordPress plugin as my contact form. I am using SMTP settings, with gmail's SMTP: Host - smtp.gmail.com Port - 465/SSL. I made sure my email/username and password are correct and I keep getting this error: SMTP connect() failed. 0 email sent. I called my host (OVH) and they said there is no blacklisted IP or blocks for outgoing emails. I am a noob when it comes to email servers so I'm not sure where to go from here. Any help is appreciated.

  Do they allow you SSH access? If so, in SSH run:
  # telnet smtp.gmail.com 465

  Ah jailed shell. Can you try connecting to your own mail server, just use your domain as the host. If that doesn't work try port 25 and 587(TLS), just to see if for some reason 465 is being blocked.

  You can test using your cPanel user. host: yourdomain.com user: cpuser@yourdomain.com password: cpuser password port: 465(SSL) 587(TLS) 25(Non SSL) Just try each one of those ports, starting with 465 to see if that specific port is the issue

  Hello, It's seems that there is an issues with the server firewall. Can you please try to disable server firewall for testing and check your plugin again.

  Hello :) You may need to consult further with your provider if you do not have root access to the system. Have them run that "telnet" command for you in the investigation. Thank you.

  I tried all 3 ports and they all took about 1 minute before showing the error: SMTP connect() failed.

  I have root access, but can't run that command. I can try calling them later today tho.

  You can install telnet via "yum install telnet" if you have root SSH access to the system. Thank you.

  Do you have root access then? I was under the impression you didn't as your cpanel access level says owner.

  Ok, I got telnet installed, then entered "telnet smtp.gmail.com 465": connected to smtp.gmail.com Escape character is '^]'. Also, OVH said port 465 & 587 are open, not filtered. They recommended checking log files, but not sure how to do that.

  Do you notice the same problem if you switch to port 25 (non-SSL) instead of port 465? Thank you.

  The issue eventually with your server firewall. Can you try with disabling firewall? Have you installed CSF?

  My host said its not firewall, but I can try disabling it. How do I disable the firewall?

  You can install a third-party firewall management utility such as CSF: ConfigServer Security & Firewall Then, since it manages your firewall rules, you can simply disable CSF through WHM instead of using the command line to manually turn off iptables. Thank you.

  Fixed. I signed up with MailJet and their SMTP works perfectly. Maybe it was an issue with my Google account.
