当我配置中继系统时，sendmail仍然通过estmp发送。

Question

我试图将sendmail配置为通过外部smtp服务器中继邮件：

sendmail.mc

include(`/etc/mail/m4/dialup.m4')dnl
include(`/etc/mail/m4/provider.m4')dnl
dnl # 
dnl # Default Mailer setup
define('SMART_HOST','212.227.15.142')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
FEATURE(`authinfo')dnl 
MAILER_DEFINITIONS
MAILER(`local')dnl
MAILER(`smtp')dnl

Authinfo文件

AuthInfo:212.227.15.142 "U:myuser@mydomain.es" "I:myuser@mydomain.es" "P:*********" "M:LOGIN PLAIN" 

每次更改后，我都会这样做：

m4 sendmail.mc > sendmail.cf
makemap hash authinfo < authinfo
make

所有命令都没有问题地执行。

但是，当我使用mail() php函数在var/log/mail.log中发送邮件时，我得到：

(我试图发送到****@gmx.com邮件地址)

Jul  6 09:05:06 ubuntu sendmail[63599]: w667561E063599: to=*****@gmx.com, ctladdr=********@mydomain.es (33/33), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30208, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (w66756Vp063600 Message accepted for delivery)
Jul  6 09:05:06 ubuntu sm-mta[63602]: w66756Vp063600: to=<*****@gmx.com>, delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=120544, relay=mx01.gmx.net. [212.227.17.4], dsn=4.0.0, stat=Deferred: Connection refused by mx01.gmx.net.

我认为sendmail不读取smtp凭据或其他内容(ip 212.227.15.142 (智能版)不在日志中)。

更新

当我尝试：

sendmail -v -s "test" rj1000@gmail.com 

因此，我没有看到smtp身份验证或智能ip的任何跟踪。

我假设日志必须表明“通过中继”而不是“通过esmtp"，在我的配置中有问题。

<#>EDIT 2

由于任何原因，我必须直接修改sendmail.cf，因为sendmail.mc修改和下一个"make“操作。现在智者开始工作了。

Answer 1

问题是，sendmail.cf没有从make命令中更新。我建议检查sendmail.cf内容或直接修改它。使用这个命令，我最终要实现从mc创建一个有效的cf文件：

m4 sendmail.mc > sendmail.cf

Answer 2

日志指示中继=mx01.gmx.net。

7月6日09:05:06 ubuntu : w66756Vp063600: to=\*\*\*\*\*@gmx.com，delay=00:00:00，xdelay=00:00:00，mailer=esmtp，pri=120544，中继= mx01.gmx.net。，dsn=4.0.0，stat=Deferred: mx01.gmx.net拒绝连接。

它试图中继，但是运行在mx01.gmx.net上的SMTP服务器不接受中继

Connection refused by mx01.gmx.net.

只需将mx01.gmx.net配置为允许从MTA中继。
