Hi all, 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? Thanks, Daniel Bruno -------------- next part -------------- An HTML attachment was scrubbed...
