today another problem with a WordPress plugin. With Contact Form 7.
I am using this plugin already a while in my blog and today it wanted to be updated.
I’ve done it and checked straight if it is still working. And no, it wasn’t working anymore There was just the message “Failed to send your message. Please try later or contact administrator by other way.” and that’s it
Although all settings was correct it wasn’t sending any emails. After a bit trying around I could found the solution by accident. It is a bit abstract, but it is working.
In the settings for Contact Form 7 is a point “From: [your-name]”. That shouldn’t be there. There have to be the email address of the blog/domain. Means the email address which is registered on the server.
It seems like else there is a conflict (spam alarm) in the system. Because it’s usually not allowed to send emails with an email address of an other domain. That is what spammer do. For example: Your blog domain is “www.abcd.com” and the email address of the sender, in the Contact Form 7, is “[email protected]”. The form is trying to send now an email with the sender “[email protected]” from the domain “www.abcd.com”. … Obviously a try to send spam … for the server.
