Update! auskie reports that the server name has changed:

Update #2, MikeStammer reports that it's not all as easy as it should be:

Update #3 (07-28-06) from parkut

The first thing to do is enable the proper directives in your sendmail.mc file to allow for the Sendmail authentication mechanisms.

Uncomment or add the following options into your sendmail.mc (usually found in /etc/mail/cf/cf/ )
define(`confAUTH_OPTIONS', `A')dnl define(`confAUTH_MECHANISMS', `LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl TRUST_AUTH_MECH(`LOGIN PLAIN DIGEST-MD5 CRAM-MD5')dnl FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl
If you want all of your outbound email to relay through SBC because you are using a dynamic source IP, also add the following SMARTHOST config into your sendmail.mc file:
define(`SMART_HOST', `esmtp:[smtp.sbcglobal.yahoo.com]')dnl
If you only want to use SBCYahoo's mailserver as a relay in the event that your mailserver can not forward email directly, add the following FALLBACK_MX config to your sendmail.mc file:
define(`confFALLBACK_MX', `esmtp:[smtp.sbcglobal.yahoo.com]')dnl
The format of these entries with brackets [ ] is key to making it work properly. The brackets keep Sendmail from looking up the MX record for the hostname which would return the bogus hostname nomail.yahoo.com. Without brackets Sendmail would bounce every message it attempted to relay through this host.

Once the above is completed, rebuild your sendmail.cf file using:
m4 /path/to/m4.cf /etc/mail/cf/cf/sendmail.mc > /etc/mail/sendmail.cf
Enter the paths for your specific site configuration as necessary in the above command.

Next we need to create the authinfo file which will contain the user credentials for logging into the mailserver. Create a file called 'authinfo' in /etc/mail/ For security reasons, this file should be chmod 400 and owned by root if you are running Sendmail as root. If you are using an alternate UID/GID for Sendmail then make sure that the file's group owner matches and set the file chmod 440. In the entry below, replace userID with your SBCGlobal username and password with your password.

Following is the syntax for the file (all on one line):
AuthInfo:smtp-sbc-v1.mail.vip.sc5.yahoo.com "U:userID@sbcglobal.net" "I:userID@sbcglobal.net" "R:sbcglobal.net" "P:password" "M:PLAIN"
The mailserver hostname is entered right after AuthInfo: in this file. Sendmail looks at the DNS A record for the host it is connecting to and parses the authinfo file looking for this hostname to match for credentials to use. If you do an nslookup for smtp.sbcglobal.yahoo.com you will notice that it is an alias or CNAME to the hostname entered above. If this ever changes, you will have to change this hostname in your authinfo file to match and rebuild the map file and restart sendmail. If you used smtp.sbcglobal.yahoo.com as the server name in the authinfo file, you would never match credentials and email would bounce from SBC for no authentication.

Once you have saved this file you need to build the authinfo map file.
makemap hash /etc/mail/authinfo < /etc/mail/authinfo
Mandrake Linux includes all the nice service start/stop scripts for standard services in /etc/init.d In the script for Sendmail they include functions to automatically rebuild the map files whenever you start or restart the service. I just added authinfo into the list of maps to build...

for i in virtusertable access domaintable mailertable genericstable authinfo; do if [ -f /etc/mail/$i ] ; then makemap hash /etc/mail/$i < /etc/mail/$i fi done
Now it is time to start or restart Sendmail. If you are going to be using the fallback MX option, I suggest initially configuring using the SMARTHOST for testing purposes and then switching back after you have verified that your config works.

service restart sendmail or
service start sendmail

Troubleshooting

Once you have Sendmail up and running with the new configuration it is time to test. Use the SMARTHOST option as recommended above during testing so that all mail goes outbound through SBCYahoo's mailserver. Send an email to an outside email address you can check and verify that you do not get a bounce back like this...

The server responded: 530 authentication required - for help go to http://help.yahoo.com/help/us/sbc/dsl/mail/pop/pop-11.html
If you get the email on your external mail account, check the SMTP headers if you can and verify that the email passed through SBCYahoo's mailserver. You may also see an Authenticated bits header, as well.

If you get the dreaded bounce back, there are quite a few things you can do to troubleshoot this problem.

Verify proper configuration

•Check the output from 'sendmail -d0.1 -bt < /dev/null'
The string "SASL" or "SASLv2" should appear somewhere in the output. If not, you didn't compile suitably.

•Check the output from 'echo "/map authinfo authinfo:smtp-sbc-v1.mail.vip.sc5.yahoo.com" | sendmail -bt'
That will check whether the authinfo map is being properly recognized.

•From the command line on your mailserver do the following:
telnet smtp.sbcglobal.yahoo.com 25 Trying 66.163.171.137... Connected to smtp.sbcglobal.yahoo.com (66.163.171.137). Escape character is '^]'. 220 smtp812.mail.sc5.yahoo.com ESMTP EHLO domain.com 250-smtp812.mail.sc5.yahoo.com 250-AUTH LOGIN PLAIN 250-PIPELINING 250 8BITMIME quit 221 smtp812.mail.sc5.yahoo.com Connection closed by foreign host.
Make sure you are getting the 250-AUTH LOGIN PLAIN option back when you enter the 'EHLO domain.com' command. If not, you have a firewall that is inspecting or filtering SMTP at the application layer. Do not use the Cisco PIX fixup protocol for SMTP or the Cisco IOS 'ip inspect' commands for SMTP on outbound SMTP sessions. This breaks the ability to authenticate SMTP sessions because it blocks the EHLO responses and spoofs a 502 response to your server. Your mailserver will never see the AUTH LOGIN option and will never even try to send its user credentials.

•You can observe a session by creating a dummy email message in a file, then run 'sendmail -Am -v -t < /path/to/file'. The file should have To:email@externaldomain.com on the first line at a minimum.

For most users, removing the port 25 filter should be the last choice. If you can't use the AT&T Yahoo SMTP server then here are your options:

1. Contact your mail hosting provider for information about using Port 587 for sending authenticated outgoing email. Since December 1998, Port 587 has been the Internet standard (RFC2476) port for authenticated email submission for mail clients and is supported by most major mail hosting providers.

2. Or contact your mail hosting provider for information about using other alternative access methods to connect to their mail server, such as VPN, Web mail or Outlook Web Access to send outgoing email.

3. Or change your email software to send outgoing mail messages through AT&T (SMTP) email servers, The AT&T (SMTP) server requires authentication using the same Master Account Member ID and password used for the POP server and PPPoE login, you are allowed to use other email domains for your email address.

Change only your Outgoing mail (SMTP) to use AT&T email servers.
Do not change your Incoming email server (POP3/IMAP).
An example of SMTP authentication settings

4. Or if none of the proceeding alternatives work, request removal of the Port 25 filter. Use the Abuse of Service Form to contact the AT&T Abuse team and choose the **Opt Out Port 25 under Abuse Type. Enter your Master Account Member id (also used for PPPoE Login) to opt-out. You don't need to enter your email address at the other mail hosting provider; the filter is based on your login ID only. After you receive a confirmation email to the Master Account Member ID (this sometimes takes 24-48 hours), you will need to logoff the network and turn off your DSL router/modem for 30 seconds to remove the filter.
An example of the Abuse Form

Also as an alternative to port 587, some third-party email providers use port 465, the "designated" Secure SMTP port. AT&T Worldnet and AT&T Yahoo are examples.
