If you send a test outbound email, the shipment will proceed properly, but the speed will be too slow.

now installed sendemail.

Forum Membership Emails are incredibly slow.

The Ubuntu terminal shows fast sending speed when tested.

The option to send an email is the default setting.
Default
Set return path with -f parameter (recommended, but does not work on all servers)


Do I need to add settings for a sendemail connection to zenrofo?
