I am trying to set up sendmail for our company on a CentOS 6.6-Release server. Specifically, I want to use SSL, so that passwords are sent encrypted.
ls /etc/mail/ssl intermediate.crt ourdomain.crt ourdomain.csr RapidSSL_CA_bundle.pem
All right, so I set up my sendmail.mc with these lines:
define(`confCACERT_PATH', `/etc/mail/ssl') define(`confCACERT', `/etc/mail/ssl/RapidSSL_CA_bundle.pem') define(`confSERVER_CERT', `/etc/mail/ssl/ourdomain.crt') define(`confSERVER_KEY', `/etc/mail/ssl/ourdomain.key')
I'm not entirely sure that the certificates are correct...
And then ..
DAEMON_OPTIONS(`Port=smtp,Name=MTA') DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')
At this point, I can send and receive e-mail from localhost (logged in and using mutt), and from within our network. But I can't add my e-mail account to an iPhone, or an iPad, and that's what the bosses want.
So I want the only connections to be on port 465, so I comment out this line:
I then rebuild sendmail.cf..
m4 sendmail.mc > sendmail.cf
I restart sendmail, and I try to send an e-mail from localhost..
[Feb 11 14:59:30 mail sm-msp-queue: t1BEs2kT005208: firstname.lastname@example.org, ctladdr=me (500/502), delay=00:05:28, xdelay=00:00:00, mailer=relay, pri=420515, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]
Sendmail is definitely running..
[root@mail mail]# ps -ef | grep sendmail root 5581 1 0 15:06 ? 00:00:00 sendmail: accepting connections smmsp 5590 1 0 15:06 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue root 5598 3296 0 15:12 pts/0 00:00:00 grep sendmail
And in /etc/mail/local-host-names, I have:
localhost mydomain.com mail.ourdomain.com[/code]
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 mail.mydomain.com ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.13 mail.ourdomain.com
I can't fathom why sendmail is refusing connections from localhost...
