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,
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.
