Why does the mail() function take so long to send emails?

Question

PHP

Hello, I need to implement sending emails using sendmail. I work on Windows, what could be the problem?
sendmail.ini:

; 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.mail.ru
 
; smtp port (normally 25)
 
smtp_port=2525
 
; 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
 
; 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=mail.ru
 
; 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=
 
; if your smtp server requires authentication, modify the following two lines
 
[email protected]
auth_password=password
 
; 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
 
[email protected]
 
; 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=mail.ru

Dispatched or delivered? mail() returns the result of the send.
