1.1 News Mail & DNS servers
Just use your normal @ameritech.net or @sbcglobal.net login and password.
1. Open your email client program.
2. Locate the email account settings for your particular client.
3. Change or set the POP (incoming) server to inbound.att.net.
4. Change the SMTP (outgoing) server to outbound.att.net.
5. For inbound email, connect securely over the standard POP3 SSL
port: 995. Use username and password. Do not use "Secure Password
6. For outbound email, connect securely over the standard SMTP SSL
port: 465. Use the same credentials as for the inbound email.
More info is available at http://www.att.com/esupport/article.jsp?sid=KB401570&cv=804&title=Email+server+settings+(POP+and+SMTP).
Important note: These servers require authentication, so you will have to enter your username into your news reader (firstname.lastname@example.org or @sbcglobal.net) and enable authentication by username and password to gain access. qsg1049 reports that both primary and secondary usernames now work, and can have 3-4 simultaneous connections to the server.
PLEASE NOTE if you find an error please send it to RadioDoc .

got feedback? reports that the server name has changed:
smtp.sbcglobal.yahoo.com canonical name = smtp-sbc.mail.yahoo.com.
smtp-sbc.mail.yahoo.com canonical name = smtp.sbc.mail.yahoo4.akadns.net.
Update #2, MikeStammer reports that it's not all as easy as it should be:
I think SBC just broke SMTP AUTH again in things like sendmail and postfix. this morning i had errors at 2 sites. seems they changed the IP that smtp-sbc-v1.mail.vip.sc5.yahoo.com was resolving to. i had to hard code the IP of what smtp-sbc-v1.mail.vip.sc5.yahoo used to resolve to to get it working again. The old IP (the one that works) is 188.8.131.52. if you resolve the IP based on the hostname now and try to SMTP auth (at least with sasl) it doesnt work. it complains that authentication is needed.
Further update and a possible fix at »Warning: SBC Yahoo SMTP Auth possibly broken
Update #3 (07-28-06) from parkut :
I discovered my configuration for using SBC and Sendmail as my MTA was broken. I spent some time googling around, and found a hint on another website. Here is the result of how I fixed it.
edit the file /etc/mail/authinfo Below is the contents of my authinfo file AuthInfo:yahoo.com "U:email@example.com" "I:firstname.lastname@example.org" "P:pAsSWoRd" "M:PLAIN" AuthInfo: "U:email@example.com" "I:firstname.lastname@example.org" "P:pAsSWoRd" "M:PLAIN" In case its not apparent, the text after U: and I: is the username, after P: is the password Note that the second line is almost exactly the same as the first line except its missing yahoo.com and there is a space after the colon. I'm not exactly sure why this line is needed, but it did not work until I added it. After editing the file, run the following command to secure the file: chmod 660 /etc/mail/authinfo Then convert to a .db file so sendmail will recognize our new settings: makemap hash /etc/mail/authinfo < /etc/mail/authinfo----------
SBCYahoo's mailserver requires user authentication in order to relay email through it. This causes a problem if you want to run a mailserver with your own domain name on your home network and relay your outbound email through SBCYahoo's mailserver. You may want to use SBCYahoo as a SMARTHOST for all of your outbound email because you have a dynamic IP address and no mailservers out there will accept email from you because they are running RBL filters that block your IP. You may want to just use SBCYahoo's server as a fallback MX host in the event that your mailserver can not send directly for whatever reason. There are a number of configuration issues that can make this tricky to setup and the available documentation is less than helpful in understanding how to resolve these problems.
Following is a little tutorial that will hopefully clear up these issues and save you hours of frustration wondering why you keep getting authentication errors etc. This configuration is based on Sendmail 8.12.10 running on Mandrake Linux 9.2 with Linux kernel 2.4.22. This FAQ assumes you already have Sendmail compiled and installed and configured as your mailserver, that you understand the basics of Sendmail configuration, and you are logged in as root. If you need assistance with building Sendmail for authentication see Jon Fullmer's great tutorial.
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:
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:
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 sendmailor
service start sendmail
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.
Verify mailserver output
•From the command line on your mailserver do the following:
telnet smtp.sbcglobal.yahoo.com 25 Trying 184.108.40.206... Connected to smtp.sbcglobal.yahoo.com (220.127.116.11). 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@example.com on the first line at a minimum.
To use the old behavior (no MX lookups), you have to put the fallback server's domain name in square brackets in your .mc configuration file and run it through m4 again, copy it in place of your current config and restart sendmail.
Below is the line you need to add or replace in your sndmail.mc file. If you use a different FallBack MX host, then just change the domain name inside the square brackets to the server you use.

Open up a telnet session on port 110 to pop.sbcglobal.yahoo.com. Go to a command prompt and type:
TELNET pop.sbcglobal.yahoo.com 110 (or whatever format your OS requires for Telnet)
and enter the following:
USER firstname.lastname@example.org (or email@example.com depending on your account domain)
PASS your password
If it doesn't accept the password, change it through the main account's page at »sbc.yahoo.com.
If it does, type:
See if anything looks funky there.
RETR followed by a number will display a message. If you want to delete it, type DELE followed by that number.
QUIT should get you out of the session.
See if this gets you on the road.

To use Option 3 your AT&T Yahoo! DSL email must work. If you did not complete the Yahoo portion of AT&T Yahoo! DSL registration, your email may not be setup. If you can log on to www.sbc.yahoo.com please ignore this note.
If you cannot log on to att.yahoo.com please read this FAQ
How do I register a username and password for my new account?
Port 25 is not blocked; anything outbound on port 25 that is not destined for a AT&T Yahoo mail server is not routed past the Redback.
1) Open a command prompt. If you can't find the little sucker in Windows just hit "start", click on "run" and type cmd. If you are running Linux or a derivative, we'll just assume you already know how to run Telnet on a port other than 23.
2) In that command prompt "DOS box", type telnet mail.dslreports.com 25 which will result in one of two results:
a) NOT blocked:
If you get "a)", then your mail server or client has issues other than a port block by SBCIS. If you get "b)" and need to use servers other than what SBC provides, see »AT&T Midwest/Ameritech FAQ »Here's what to do if port 25 is blocked for you.
