I've been unable to figure this out. No mail is being recieved and there are a lot of entries in the maillog that look like this:
Aug 19 18:05:15 server1 postfix/smtp: 9E79D3B097D: to=<firstname.lastname@example.org>, relay=none, delay=193201, status=deferred (connect to lycosbox.com[188.8.131.52]: server refused to talk to me: 421 SMTP service not available, closing transmission channel )
This was working the other day, but I'm sure I did something to break it. Could this be a firewall issue. I've tried sending mail locally as well with no luck. Here is the message I get when I try to send to a local recipient.
Aug 19 18:11:32 server1 sendmail: j7K1BW5n024509: to=admispconfig@localhost, ctladdr=web1_twoods (10001/10001), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30107, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (Ok: queued as 70AE83B0978)
It looks like it sent, but there is no message in the in box. Thanks for your help.
