XF 2.1 Email transport method best practice: Default or SMTP?

[Jon12345]

I am not sure what the difference is between these two transport methods. Anyone know?

Is the email transport method just for emails sent out from the software, or for receiving too? Unsure if I should be using SMTP instead of Default.

Most of the time, you can use either but Default is easier to set up.

I used SMTP on one forum only because Default (php) wasn't working well on that server. To be honest, I can't even remember what the issue was but SMTP fixed it.

So basically, my advice would be to go with the default php mailer unless you encounter problems.

Is it safe to switch from one to the other for a few days and then back again?

Is all that is invlolved changing the option button?
