Sendmail：“TLSvalidation=失败”，“554 5.1.8：发件人地址被拒绝：未findMXlogging”

已经挣扎了一天，找不到解决办法。当试图发送邮件给一些主机时：

Jan 5 10:31:37 vps**** sm-mta[2192]: STARTTLS=client, relay=mail-x.*****.co.uk., version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 Jan 5 10:31:37 vps**** sm-mta[2192]: u059Vb4d002190: to=<****@****.co.uk>, ctladdr=<root@vps****.ovh.net> (0/0), delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=124764, relay=mail-x.****.co.uk. [212.46.138.29], dsn=5.1.8, stat=Service unavailable

经过一些研究发现，这可能是TLS问题，所以试图禁用和添加：

 Try_TLS: NO

但是然后我得到：

 Jan 5 10:33:56 vps**** sm-mta[2375]: ruleset=try_tls, arg1=mail-x.****.co.uk, relay=mail-x.****.co.uk, reject=550 5.7.1 <****@****.co.uk>... do not try TLS with mail-x.****.co.uk [212.46.138.29] Jan 5 10:33:56 vps**** sm-mta[2375]: u059XuVY002373: to=<****@****.co.uk>, ctladdr=<root@vps****.ovh.net> (0/0), delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=124764, relay=mail-x.****.co.uk. [212.46.138.29], dsn=5.1.8, stat=Service unavailable

我的sendmail版本和设置：Ubuntu上的8.14.4

 ============ SYSTEM IDENTITY (after readcf) ============ (short domain name) $w = vps**** (canonical domain name) $j = vps****.ovh.net (subdomain name) $m = ovh.net (node name) $k = vps****.ovh.net ========================================================

有任何想法吗？

附加信息 ：

以详细模式发送testing消息会产生以下错误：

5.14：发件人地址被拒绝：未findMXlogging

Sendmail：debugging传出SMTP会话

作为根发送testing消息与SMTP会话的完全跟踪。
通常它提供了一些有用的提示。

 #!/bin/sh RECIPIENT='****@****.co.uk' # -i : sendmail will rewrite lines starting with dot # -Am : use sendmail.cf instead of submit.cf (usually requires root privileges) # -v : use verbose mode (track SMTP session to STDERR) # -- : separate command line arguments and recipients list /usr/sbin/sendmail -i -Am -v -- $RECIPIENT <<END Subject: test message To: $RECIPIENT test message body END
