Hi kellygrossjstae & all,Bug #8085
might be relevant; if emails are getting snagged because of Sender Policy Framework
implementations, it may help to solve that. We'll be testing this a little further and writing up patches for existing releases of OJS (2.3.x and 2.4.x); if you're interested in trying this, sign up to be CC'd on the bug entry for when those patches are available.
