Hello,

I have an error with sendmail.

OS: Windows server 2008 R2
Xampp: 1.7.4

My php.ini configuration file:

[mail function]
SMTP = smtpapl.dominio.xx
smtp_port = 25
sendmail_from = soportegrm@dominio.xx

My sendmail file:

smtp_server=smtpapl.dominio.xx
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=dominio\user
auth_password=password

We enable sendmail.exe in our firewalls and antivirus. But still not workin, log file error is:
11/10/24 13:58:57 : Service not available, closing transmission channel<EOL>
