XF 1.5 Email hostname fails - after error fixed will emails be resent?

[creativeforge]

Hi all, we had 22 pages of server errors this morning (recent email options settings had a typo). They were fixed, but I'm wondering what will happen with all these unsent emails (over 500), which I assume are notifications and registrations confirmations. Will Xenforo try to resend them all once again?

Thank you in advance!
