Hi j-ed, thanks for offering to help. Here is the section from my config.php that has the smtp settings:
‘mail_smtpmode’ => ‘smtp’,
‘mail_smtphost’ => ‘smtp.mailgun.org’,
‘mail_smtpport’ => ‘587’,
‘mail_smtpauth’ => true,
‘mail_smtpauthtype’ => ‘login’,
‘mail_smtpname’ => ‘postmaster@mydomain.com’,
‘mail_from_address’ => ‘postmaster@mydomain.com’,
‘mail_domain’ => ‘mydomain.com’,
‘mail_smtppassword’ => ‘redacted’,
In the settings with mydomain.com, mydomain is not what’s in the config. Just redacting it for security.
