XF 1.2 Email server questions

[AzzidReign]

I want to have a separate email server but we get hit with DDoS a lot. I wanted to know if the email server went down, will a queue be built up and when the server is back up, will that queue be sent to the email server? Or will any email that was suppose to be sent out while the server is down be lost?

XenForo doesn't manage a queue, no.
