Estou tentando configurar o sendmail para retransmitir email por meio do servidor smtp externo:
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
Arquivo Authinfo
AuthInfo:212.227.15.142 "U:[email protected]" "I:[email protected]" "P:*********" "M:LOGIN PLAIN"
Após cada alteração, faço isso:
m4 sendmail.mc > sendmail.cf
makemap hash authinfo < authinfo
make
Todos os comandos são executados sem problemas.
Mas quando eu envio um e-mail usando a função mail() php em var/log/mail.log , obtive:
(Eu tento enviar para ****@gmx.com endereço de email)
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.
Eu acho que o sendmail não lê as credenciais smtp ou algo assim (ip 212.227.15.142 (smarthost) não está no log).
UPDATE
Quando eu tento:
sendmail -v -s "test" [email protected]
Eu obtenho isso, portanto, não vejo nenhum traço da minha autenticação smtp ou ip smarthost.

Suponho que o log deve indicar "via relay" e não "via esmtp", algo está errado na minha configuração.
EDIT 2
Por qualquer motivo, eu tenho que modificar o sendmail.cf diretamente, porque a modificação do sendmail.mc e a próxima ação "make". Agora o smarthost está funcionando.
O log indica relay = mx01.gmx.net.

Ele está tentando retransmitir, mas o servidor SMTP em execução em mx01.gmx.net não aceita retransmissão
Connection refused by mx01.gmx.net.
Basta configurar o mx01.gmx.net para permitir a retransmissão do seu MTA.
