Hello, I have been having this issue for some time now and cant seem to narrow it down. We have one vendor we cant email. Everytime I lookup the error it states their server does not have sufficient disk space. I have redacted our server info. I cant seem to figure out where the error is coming from because they keep telling me their server has sufficient space. I also performed a couple of MX tests and their server seems to fail the TLS tests.
