POP3 works but SMTP seems fishy...

[rmrf]

Here is my setup:

Redhat 8.0
Apache 2
PHP
MySQL
Postfix
UW-IMAP
BIND 9

(I think that is all the pertinent information.)


Right now I have my web server set up to host 2 domains. I have email running for 1 of the domains, and I would like to get the other one working as well, from the same machine. I have everything set up in Postfix they I believe it should, it's just when I try setting up the 2nd domains email account with Outlook Express, I can receive mail, but I get an error everytime I try to send. Here is the error:

The connection to the server has failed. Account: '<accountname>', Server: '<servername>', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

I have googled this, and this is the link from Microsoft's site that I get:

That is all fine and dandy, except for the fact that I am not on and MSN network. Are they just using an MSN network as an example, or is that the answer? Anyways, so I looked into setting up squirrelmail and saw that there is a "multilogon" plugin that allows the user to choose which IMAP server they want to log into. I am able to log in fine with this plugin, but whenever I try to send mail from the 2nd domain, it uses the 1st domain's SMTP setting, so it is coming from the wrong address. What am I doing wrong here? Does logging into an IMAP server allow the download of folders only, and there is only one SMTP server that can be used?

Sorry about the long post, but I wanted to be as detailed as possible. Thanks a ton for whoever can help me on this.

 

[rmrf]

anyone?

I not a Linux person, but I will bet it has to do with your SMTP server permissions on outgoing mail on the SMTP server.

I can take that two ways:

1. Port 25 is not open to traffic on the server's network.
2. Port 25 is not open to traffic on the client's network.

I have a business class line, so everything is kosher on the side of my server. However, could it be that the networks I am setting these up on do not allow any use of port 25 unless it is with their relay? I guess it is possible that I will have to set it up so that it uses 110 to receive mail from my server, and then use whatever the relay is for the network they are on. BTW, the client is on a dial-up network, so that is possibly why this is causing me so much trouble.

thanks for getting the wheels turning.
