No. ISPs reject, file as spam or silently discard messages based on criteria that only the individual ISPs understand completely and they won't reveal their methods because they think it aids spammers. Even if they are blocking a sending server by IP, that might not apply to all list mail if the host has multiple outgoing servers. Note that if the undelivered posts are all From: aol.com and/or yahoo.com, it may be a DMARC issue.
