传出的电子邮件没有被encryption

我正在使用postfix发送电子邮件。 我有mysql设置来pipe理域,帐户和别名。 我有3个域名设置。 一个域是主要的域,当发送电子邮件到Gmail帐户一切正常。 ssl证书仅适用于主域。

当我使用任何虚拟域名发送电子邮件到一个Gmail帐户,他们被标记为垃圾邮件。 gmail给的原因是电子邮件是未encryption的。 它认识到发送邮件的邮件服务器是主服务器。 Postfix被configuration为只使用tls

为什么来自虚拟域的邮件不能以encryption方式发送?

如果有帮助,我可以提供任何其他信息。

这是来自电子邮件的标题,configuration了DMARC和SPF。

你需要一个有效的SSL证书和你的Postfix服务器的私钥设置,在你的main.cfg文件中有这样的行

smtpd_tls_cert_file = /etc/pki/tls/certname.crt smtpd_tls_key_file = /etc/pki/tls/certname.key smtpd_tls_CAfile = /etc/pki/tls/ca.bundle smtpd_tls_protocols = SSLv3,TLSv1,!SSLv2 smtp_tls_protocols = SSLv3,TLSv1, !SSLv2 smtpd_tls_cipherlist = ALL:!ADH:RC4 + RSA:+ HIGH:+ MEDIUM:-LOW:-SSLv2:-EXP:-eNULL smtp_tls_cipherlist = ALL:!ADH:RC4 + RSA:+ HIGH:+ MEDIUM: -SSLv2:-EXP:-eNULL
