asi es en windows
Descargá sendmail desde aqui
http://glob.com.au/sendmail/
descomprimi el ejecutable en una carpeta, ej C:\sendmail
luego, es php.ini, en la sección mail
[mail function]
; For Win32 only.
;
http://php.net/smtp
SMTP = localhost
;
http://php.net/smtp-port
smtp_port = 25
; For Win32 only.
;
http://php.net/sendmail-from
sendmail_from =
[email protected]
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
;
http://php.net/sendmail-path sendmail_path = "C:\sendmail\sendmail"
la linea en negritas es la ruta en la que descomprimiste el ejecutable
luego, en esa carpeta vas a encontrar un archivo llamado sendmail.ini, completalo con los valores requeridos, te dejo el mio de ejemplo
Código INI:
Ver original; configuration for fake sendmail
; if this file doesn't exist, sendmail.exe will look for the settings in
; the registry, under HKLM\Software\Sendmail
[sendmail]
; you must change mail.mydomain.com to your smtp server,
; or to IIS's "pickup" directory. (generally C:\Inetpub\mailroot\Pickup)
; emails delivered via IIS's pickup directory cause sendmail to
; run quicker, but you won't get error messages back to the calling
; application.
smtp_server=smtp.gmail.com
; smtp port (normally 25)
smtp_port=465
;smtp_port=25
; SMTPS (SSL) support
; auto = use SSL for port 465, otherwise try to use TLS
; ssl = alway use SSL
; tls = always use TLS
; none = never try to use SSL
smtp_ssl=auto
;smtp_ssl=none
; the default domain for this server will be read from the registry
; this will be appended to email addresses when one isn't provided
; if you want to override the value in the registry, uncomment and modify
default_domain=gmail.com
; log smtp errors to error.log (defaults to same directory as sendmail.exe)
; uncomment to enable logging
error_logfile=error.log
; create debug log as debug.log (defaults to same directory as sendmail.exe)
; uncomment to enable debugging
debug_logfile=debug.log
; if your smtp server requires authentication, modify the following two lines
auth_password=tuclave
; if your smtp server uses pop3 before smtp authentication, modify the
; following three lines. do not enable unless it is required.
;pop3_server=
;pop3_username=
;pop3_password=
; force the sender to always be the following email address
; this will only affect the "MAIL FROM" command, it won't modify
; the "From: " header of the message content
;force_sender=
; force the sender to always be the following email address
; this will only affect the "RCTP TO" command, it won't modify
; the "To: " header of the message content
;force_recipient=
; sendmail will use your hostname and your default_domain in the ehlo/helo
; smtp greeting. you can manually set the ehlo/helo name if required
hostname=gmail.com
en mi caso, que uso gmail, tengo habilitado el puerto 465 para smtp, ya que usa ssl.
Para finalizar la clase phpMailer viene con una carpeta de ejemplos, testeá con alguno de ellos
