Using nslookup to check an email blocklist

I was notified by someone today that yesterday he had sent an email to a mailing list on an email server I maintain, but the email had not been delivered to recipients. When I checked yesterday's email log, I didn't see any email from his email address, so I asked him to resend the message. He did so, but that email message was also not delivered and I didn't see any log entry for his email address in today's email log, /var/log/maillog. He has a verzion.net email address and Verizon recently transitioned its email service to AOL. I remembered helping him make that transition last month, so I looked for any aol.com entries in the log file and found the entry below for an attempt by an AOL email server to deliver a message that was rejected at the time he told me he had sent the email today.

# grep aol /var/log/maillog
