Contact Form 7 Plugin emails not being received by some accounts

Question

I am using contact form 7 to send an email form. I receive them, but my clients' email addresses - one at the host and one at gmail, never do. They claim that none of the messages end up in their spam folders either. The client did ask the host to take a look and they also claimed that there is no blocking of the form emails and they aren't being sent to spam. Ideas on where things are going wrong and how to fix this?

Answer 1

I have had tons of issues with the plugin Contact Form 7 in the last couple months. Especially with Wordpress 3.5.1. I started using Formidable Pro for all of my clients in the last couple weeks. It costs a bit of money for the developer license, but the peace of mind that it is working and there is plenty support as well as additional plugins available has been priceless!

In the event that it is not Contact Form 7 that is causing the problem of sending mail check/do the following.

• Make sure the IP Address the site resides on is not Blacklisted
• Check to see if the server is set to deal with mail internally or remotely
• If all else fails, you can always configure it to send mail through an actual email account though SMTP.
