pop before smtp

[Kees]

A mail sent from a host to my smtp server is refused. This happens
because you have to connect to a pop server before you can use the
smtp server.
Does anybody have any code to achieve this (PHPmailer doesn't work)?

Greetings,
Kees

I do not recognize this problem. I had a problem with the sender of the
mail. Some smtp servers seem to be configured to allow only messages
from known domains to be sent and refuse to send it if the "from"
address has a wrong domain (I encountered it in a company that had
planned to register more domains than they eventually did.) Could this
be a problem here?

Kees,

Have you asked your hosting company? Perhaps they have another server
for programs to use, for instance.

Otherwise use the socket calls to log into the POP server and log out
again before sending the mail. If you do this, I'd recommend a separate
mail ID so you don't collide with the "real user" of the account.

Right. They do that because POP requires a username and password, and SMTP
does not. By logging in to POP, you verify that you are authorized to use
their SMTP service. It opens up a worm hole that allows you to send SMTP
mail for a short period.

You don't have to actually READ your e-mail, you just have to log in.

POP is a very easy protocol, but all you really need to do is login and
logout. You use the imap_* functions to access it.

imap_close(
imap_open( "{server.domain .com:110/pop3}INBOX" username, password )
);

My ISP requires POP authentication before sending. I use this class to
solve that problem as it supports POP before SMTP authentication as you
need:

http://www.phpclasses.org/smtpclass

I use and recommend it to use in conjunction with this MIME message
class that everything PHPMailer does and more. It can use the SMTP class
above to deliver properly composed messages:
