Question:
Hi,
I have a fresh install of Ubuntu 8.04 Server where EHCP latest version was installed last week. Until today near everything is working fine. I have some apps not working and with errors like “Sys. Information” but I’ll discuss this problems later. For now I’m much more concerned with the e-mail server thing. The system can send and receive e-mails normally using Squirrel mail web interface, but when I try to configure an e-mail client like “Microsoft Office Outlook” I have a bunch of errors with the SMTP connection. I have tried everything that I found in your forums and help files with no results. I work with hosting in Windows Server environments since 1998 but with Linux I’m a complete newbie. I think that the problem could be with the SMTP port. In my last Windows 2003 server I had an arrangement that the SMTP used ports 25 and 587 because some ISPs here in Japan and other countries are blocking port 25 for spam reasons. I would like to try to do the same ar
rangement with Ubuntu but I don’t know how! What are the commands and where to look for in Ubuntu or EHCP? What I’ll have to do to configure Outlook? Where can I find in the system (or in EHCP) information about the “mail.domain.com”, “port numbers”, and all other stuff related to the mail server (postfix)…?
Regards,
Answer:
mail system name may be one of:
www.yourdomain.com
yourdomain.com
mail.yourdomain.com
as long as you host all in one server.
normally, port 25 is setup by default,
you need to test outlook connection using pop3, with ssl/tls settings,
try tls, ssl one by one in outlook.
Dont forget to include @domain.com in your email username.
as you mentioned, your ISP may block your port 25.
is your server located on a datacenter, or your home such as dsl ?
if your server in home/dsl, and if your isp blocks port 25 toward your server, then you are in trouble, you need to make your ip static, and ask your ISP to open port 25.
try also this:
open console, in linux,
open file using:
<code>nano /etc/postfix/master.cf
add on bottom of file:
<code>submission inet n - - - - smtpd
save and exit
then:
<code>/etc/init.d/postfix restart
this way, your server will accept emails at port 587 rather than 25.
This may solve your problem.
Email things are hardest part of a hosting business.
in fact, it is not so hard, but, compared to other things, it is hardest. if you think, latest changes in ISP's regarding port 25/587, because of spam, email problems changes in time
on any subject, including email, debuggin your system may help you a lot in understanding and solving your problems. so, debug your system while dealing with email, as described in http://ehcp.net/?q=node/771
Good luck.
