Cannot send email from OE through ISPconfig site

[tomd]

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:

The connection to the server has failed. Account: 'bob', Server: 'packagedesign-mds.com', Protocol: SMTP, Port: 587, Secure(SSL): Yes, Socket Error: 10061, Error Number: 0x800CCC0E

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?

For any sock error on Windows, check this page for help:

http://msdn.microsoft.com/library/de...or_codes_2.asp

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:

#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!

Hello Falko,

To work with SSL in ISPConfig, or under firewall you need activate the nexts ports:

IMAPSSL 993 tcp yes
SMTPDSSL 465 tcp yes
POP3SSL 995 tcp yes

I worked, read, and practiced hard the last nights, to doing it. I'm had problem to access to IMAP SSL, I bad thinking are a problem of openssl or courier imap, but not, my problem are the firewall... I solved now...
