My Joomla site’s standard contact form is failing to deliver messages even though I’ve already double-checked the global email configuration and the SMTP details look correct. I need someone to: • Diagnose why the form isn’t sending—server mail log, Joomla mailer settings, spam or PHP mail issues. • Apply and test the fix until messages reliably reach the target inbox. • Add custom validation rules to specific fields so the form rejects incomplete or improperly formatted submissions before users can send. Please work directly in Joomla (current stable release) and leave clear notes on what you changed so I can replicate it in staging later. Once everything is patched and validated, confirm by sending a few live test emails and showing they arrive with proper headers. rs form is the problem dont sent emails to administrator
