linux sendmail 配置發送外部郵件（redhat6）

1. 建立 sendmail認證

cd /etc/ssl/certs/make sendmail.pem

 2 .添加authinfo在/etc/mail/access 中添加

AuthInfo:smtp.gmail.com “U:root” “I:User@gmail.com” “P:password” “M:PLAIN”AuthInfo:smtp.gmail.com:587 “U:root” “I:User@gmail.com” “P:password” “M:PLAIN” 

產生資料庫

makemap -r hash /etc/mail/access.db < /etc/mail/access

 

 3.配置smarthost編輯 /etc/mail/sendmail.mc在MAILER前添加

FEATURE(`authinfo',`hash /etc/mail/access.db')dnldefine(`SMART_HOST',`smtp.gmail.com')dnldefine(`RELAY_MAILER_ARGS', `TCP $h 587')define(`ESMTP_MAILER_ARGS', `TCP $h 587') define(`CERT_DIR', `/etc/ssl/certs')define(`confCACERT_PATH', `CERT_DIR')define(`confCACERT', `CERT_DIR/ca-bundle.crt')define(`confCRL', `CERT_DIR/ca-bundle.crt')define(`confSERVER_CERT', `CERT_DIR/sendmail.pem')define(`confSERVER_KEY', `CERT_DIR/sendmail.pem')define(`confCLIENT_CERT', `CERT_DIR/sendmail.pem')define(`confCLIENT_KEY', `CERT_DIR/sendmail.pem') define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN') 

寫入到sendmail.cf中

m4 sendmail.mc > sendmail.cf
