XF 1.5 Unable to send mail (User confirmation, 2FA emails, etc)

I'm constantly getting this error log:
https://gist.githubusercontent.com/...4c4752c79e48217c6febae185eefdd4/gistfile1.txt
whenever users try to send mail. Currently the MTA is sendmail, but it also occurs with postfix.

For a bit of background, I've confirmed that sendmail via terminal will send mail properly, but sometimes the domain returns a 451, (related to spam filters).
We've also recently moved servers/ip's to a new VM.

Is there any troubleshooting I can do on the XenForo side to fix it? What can I do to fix it?

Working off a default sendmail config for now so there's a starting point.

It's not that XF isn't seeing it installed, that's just one of (typical) the causes of that error message.

There are others - it's something which will have to be investigated on the server, possibly even using debug code in the XF files to determine what.

I'll enable debug mode and see what I can find out.
