Cannot send email from OE through ISPconfig site

I have setup an Ubuntu 6.06/ISPConfig server using Falko's excellent howto and the the ISPConfig installation guide (which is also excellent) and all has been working well. I can send and recieve email through the webmail interface and recieve mail with Outlook Express. My problem comes in sending email through Outlook Express. I get this response:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'bob', Server: 'packagedesign-mds.com', Protocol: SMTP, Port: 25, Secure(SSL): Yes, Socket Error: 10053, Error Number: 0x800CCC0F

This area's largest DSL provider blocks port 25 - and I am testing from that provider's service. So I suspect my access to the server is being blocked. Plus, I cannot see any evidence of a login attempt in the server logs. The provider says that I should access any off-network mail server using port 587, but if I change the smpt port from 25 to 587 (in OE) I get this:

Is it possible to send email through the ISPConfig based domain's email server from outside its network?

Yes, that's right.

What's in /etc/postfix/master.cf?

Code 10061
Connection refused.
No connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host???that is, one with no server application running.

Please comment out these two lines in your master.cf:

Code:

#smtps    inet  n       -       -       -       -       smtpd

#  -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes

and restart Postfix. It will make Postfix listen on port 465.

You are the master.

Since those lines were already commented, I think you meant to say "uncomment" rather that "comment out". (I removed the hash marks) But that did the trick and I was able to send from DSL and Cable providers.

Your Howto guides are outstanding. Thank you for this site!

Yes, right. Sorry about that.

No probem. I just love the clarity of your guidance. Instead of answering "Just turn on smpts" you give the details that I can learn from. Because of the clarity of the instructions, I could easily see where the intention was reversed. Thank you again.

Same issue but socket Error

Hello
I experience the same issue using Postfix on UBUNTU 6.06.
I can receive messages using OE but I'm unable to send them.

This is the error I got:

"Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'mail.geoaec.com', Server: 'smtp.geoaec.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F"

Microsoft Winsock REF : Error 10053 (DB-Library)
Severity Level 2
Message Text: Attempt to bulk copy a null value into a server column that does not accept null values.

How do I fix that issue?

Thanks

The problem is that also your ISP is blocking port 25.
The way you can fix this is the exact same way as he did (that is if your ISP did not close port 465)
Read "falko's" reply. You will need to set OE's SMTP port to 465.
