Hello,
Thanks for reaching out to us.
Since PHP Mail can sometimes be blocked by hosting providers (including IONOS) due to security restrictions, we recommend switching to SMTP for sending emails. SMTP is more reliable and ensures better email deliverability.
You can configure SMTP using the following details:
• SMTP Host: smtp.ionos.de/ or check on your hosting email settings.
• SMTP Port: 587 (or 465 for SSL)
• Encryption: TLS or SSL
• Username: Your full email address ([email protected])
• Password: Your email password
You can set this up under:
System > Global Configuration > Server > Mail Settings
This should resolve the issue. Let us know if you need further assistance!
Thanks,
