I fear that some potential list members are unable to get confirmation
requests through. I've verified that I can subscribe and unsubscribe
from 3 of my accounts, but on a fourth (at yahoo) I cannot confirm my
subscription. Instead, I get the following information in my mallog:
Sep 9 19:31:28 gbf1 sendmail: g8A0VRx03672: tcpwrappers
(web20405.mail.yahoo.com, 188.8.131.52) rejection
Sep 9 19:31:28 gbf1 sendmail: NOQUEUE: web20405.mail.yahoo.com
[184.108.40.206] did not issue MAIL/EXPN/VRFY/ETRN during connection to
How should I set the sendmail configuration to accept these messages?
Is this hosts.allow or sendmail.cf? I still get confused.
