imap courier postfix

I am new to Linux and am trying to install a mail server that can send and receive e-mails local and abroad.. I am running ubuntu server 12.04. I am following this post: https://help.ubuntu.com/community/PostfixBasicSetupHowto

EVERYTHING was fine until, i get to the part that says:

netcat mail.yourdomain.com 25​

@ which point i get the error:

assmin@serverb:/etc$ netcat mail.peteserve.linkpc.net 25
netcat: getaddrinfo: Name or service not known

However, if I type:

assmin@serverb:/etc$ netcat peteserve.linkpc.net 25​

I get:

220 mail.peteserve.linkpc.net ESMTP Postfix (Ubuntu)
ehlo peteserve.linkpc.net
250-mail.peteserve.linkpc.net
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
​

I can also type:

assmin@serverb:/etc$ telnet localhost imap
​

and get:

Trying 127.0.0.1...
Connected to localhost.

30 views no answers? I will add this is my 5th install... i have tried several different DIY or Sourceforge instructions and everyone leaves out VITAL details...

 

thank you for taking the time! I should have put that the first 4 times i had tried sourceforge how to's... but i could only find ones here that talked about making virtual hosts with virtual users... I just wanted the most simple install because I thought I was running into problems with virtual users.. However, after trying the one I am on now, I came to the conclusion that I must be missing something else entirely.. As this happens no matter who's tutorial i am using... BTW.. this is my /var/mail.err log:

May 18 02:09:57 serverb imapd: (null): TOO MANY CONSECUTIVE PROTOCOL VIOLATIONS​

 

This is my hosts file:

127.0.0.1 localhost
127.0.1.1 serverb.peteserve.linkpc.net serverb

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

​

I should change it to :

127.0.0.1 localhost
127.0.1.1 mail.peteserve.linkpc.net serverb

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters​

 

I am not sure what you mean by DNS? Do you mean that I setup the MX wrong?(Thank you in advance) (I plan to make a simple how-to for sourceforge once i get this up)

 

still not working...

 

I suggest you try this tutorial: http://www.howtoforge.com/virtual-u...urier-mysql-and-squirrelmail-ubuntu-12.04-lts

Works out of the box.

 

Thank you for replying! OK... so i formatted / reinstalled ubuntu12.04 Used FALKO's install with virtual servers(even though i didnt want virtual servers...) followed his instructions to the t.(for the second time) EXACT SAME ERROR! After researching for the past 6ish hours I have concluded that a large number of people have the same problem.(most give up at this point, I know because all the posts i find are never 'solved' and are months old.. This is not a new problem either. It has been happening to people for a couple years. I do not know what I am missing / setup wrong.

Congratulations, your SquirrelMail setup looks fine to me!​

and then when i log in to my server through squirrelmail, i get:

ERROR:
ERROR: Connection dropped by IMAP server.

​

 

btw, I have challenged 2 of my computer-literate friends to install this using falko.. They are almost at the same point. The only thing that i can possibly think of is that my domain is a second level domain(i got it free from dns exit) But they still allowed me to set my MX to mail.peteserve.linkpc.net 10
so.. IDK if that is even an issue..

I just realized that you are FALKO! haha.. THANK U so much for taking the time to help me.

 

So.. still trying all sorts of edits.. i thought i was keeping a close track on what i was doing and now when i try to go to squirrelmail through the web, for somereason it redirects to peteserve.linkpc.net/peteserve.linkpc.net/whatever... IDK why it is adding the extra peteserve...
