Thanks for pointing me the solution. * Nevertheless the plugin is quite old and an update would be needed. * [coloindonesia](https://wordpress.org/support/users/coloindonesia/) * (@coloindonesia) * [9 years, 8 months ago](https://wordpress.org/support/topic/wp-46-issues/#post-8231021) * thanks for the codes @ functions.php .. it works * [Ryan Hellyer](https://wordpress.org/support/users/ryanhellyer/) * (@ryanhellyer) * [9 years, 7 months ago](https://wordpress.org/support/topic/wp-46-issues/#post-8359296) * I had this problem too. I think you will find it’s triggered by the server_name being set incorrectly, or generically. If you make sure it is explicitly specified, the problem should go away. This also applies to proxies, so make sure the proxy isn’t processing every domain by default. * [mbogh77](https://wordpress.org/support/users/mbogh77/) * (@mbogh77) * [9 years, 4 months ago](https://wordpress.org/support/topic/wp-46-issues/#post-8701945) * Hi we are seeing multiple errors with a similar header and expect this to also be an issue with phpmailer * Fatal error: Uncaught exception ‘phpmailerException’ with message ‘Invalid address:( setFrom) ____@https://____.com * we have recently changed our site over to https and note that if we revert back to http we don’t have the error.
