What details should I use for a WordPress SMTP plugin?
The best SMTP details to use when configuring an SMTP plugin within WordPress when you're using {{brand.brandName}} WordPress hosting are:
Outgoing mail server: {{email.smtpHostname}}
Outgoing server port (SMTP): 587
Use the following type of encrypted connection: TLS
Using these details will allow emails to be sent via SMTP from WordPress forms or allow any other SMTP-based plugins to send.
