I have a problem with Sendmail in CentOS 5. I want use authentication for external access. I configure my sendmail.mc:
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
But when send a message, show this message:
Relaying denied. Proper authentication required.
Any idea of the error?
YES,
define(`confAUTH_OPTIONS', `A')dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
Then, These two are needed.
chkconfig saslauthd on /etc/init.d/saslauthd start
Also make sure you have the cyrus-sasl-md5 package installed if you want to use MD5 auth. By default, PLAIN auth information is disabled in sendmail...
