mail in WP4.3

Same here, updated to 4.3 and I can’t use my form. Tried 2 different smtp-mail plugins, deactivated all plugins but Contact Form 7 and SMTP. Nothing comes through.

Test mails from each SMTP plugin go through.

Stopped updates to 4.3 on all other sites.

Nevermind, my bad. It works.

I Was using WP Mail SMTP which doesn’t work well with 4.3
After deactivating this plugin, CF7 works well

I was also using WP-Mail SMTP, but even after deactivation, keep having failed to send the message originated by CF7.

@sjoerdsmeets – I always recommend strongly against people jumping to use SMTP when they are not sure why they need to use it. It creates extra complexity which can be confusing for some WordPress users.

For example with SMTP you typically need to authenticate – so you will need to make sure that any emails sent via the CF7 plugin are coming from a real email address.

@buzztone – I got the idea from you actually..

On our former hosting we had several problems with mail, and the WP Mail SMTP solved it. I made a real email address, and used that for authenticating. And that worked.

We moved our hosting recently and apparently the mail problem is not around anymore.

@sjoerdsmeets – did you notice the following note in my article:

Most users on quality WordPress hosting will not need to use SMTP. You should avoid using SMTP if possible as using SMTP can contribute to email authentication issues.

It looks like your new hosting (like many quality WP hosts) allows sending mail from WordPress with the standard recommended wp_mail method – which is good. In fact we would never use hosting that didn’t allow us to do this.

So now there is no need to use SMTP. Which is also good, because setting up SMTP introduces extra complexity, which can be confusing.

If you did need SMTP, you would need to set it up to suit the new SMTP server you are connecting to – your old settings almost certainly wouldn’t work.
