如何啟用 SMPTS (465) postfix CentOS

  • November 5, 2013

我需要幫助是啟用 SMTPS。我使用 postfix , dovecot 和 MySQL(虛擬域)。我不知道如何啟用 SMTPS(465)。我已經在“/etc/postfix/main.cf”中添加了 tls 相關設置以及密鑰和證書

作業系統:Centos 6.4 64 位

請把我的 /etc/postfix/master.cf 文件放在這裡

請幫助啟用 SMTPS。我啟用了 amavis

您必須smtpsmaster.cf. 添加這樣一行:

smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes

然後您必須對其進行配置main.cf並創建 SSL 證書,這是一個範例:

smtpd_use_tls=yes
smtpd_tls_security_level = may
smtpd_tls_cert_file=/usr/local/etc/ssl/smtp.domain.com.crt
smtpd_tls_key_file=/usr/local/etc/ssl/smtp.domain.com.key  
smtpd_tls_CAfile = /usr/local/etc/ssl/ROOTCA.crt
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_tls_session_cache_timeout = 3600s

然後,重新啟動 Postfix。
