I haven't run sendmail on a recent release, but these sorts of things have caused me grief in the past: If you want to post to an external mailserver, your "from" address has to be a real address (the domain name has to have a public IP, at the very least, that the external service can look up). They won't accept mail coming from something@localhost.localdomain, or any fictitious domain names. Your machine's hostname has to resolve properly. If your machine thinks that it is localhost.localdomain, rather than some-made-up.example.com, sending mail behaves oddly. If you've done dopey things with your /etc/hosts files, such as putting your machine hostname into the localhost lines, instead of into the lines that are associated with your ethernet port addresses, sending mail can be screwy. For what it's worth, I have a properly functioning DNS server on my LAN, and no machine names in any /etc/hosts files, just the localhost lines. Mailservers, and other servers, can do some strange shenanigans to determine their hostnames, which can trip you up, such as: Look up the hostname, find out its numerical IP, reverse look-up that IP, to find out its hostname. Or, reverse-lookup its IP to find the hostname, look up the IP for that hostname, then rinse, lather, repeat. Either as a way to find out these things, or as part of the confirmation that the addresses are correct (e.g. anti-spam techniques). If something resolves to 127.0.0.1 or localhost, in the middle of such sequences, everything goes off course from what you expected. -- tim@localhost ~]$ uname -rsvp Linux 3.14.3-200.fc20.i686 #1 SMP Tue May 6 19:23:18 UTC 2014 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
