Pop and Imap problem with Mail.app [MAC]

Dears,

First of all say hello to everybody.

Web is ok.
Squirremail is ok (I can send and receive mails)
Ftp is ok.

The problem is with the Mail.app. I can't not connect to my imap or pop sever.

I can connect with telnet outside of my house, the nmap says that the ports 25,143 and 110 are open.

nmap:

Code:

21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
110/tcp open pop3
143/tcp open imap
443/tcp open https

Any idea??

I am using ubuntu server 9.10.

Thanks a lot!

 

What is the exact error you get when connecting to your server with mail via pop / imap?
Any messages in the logs by this time (/var/log/mail.log, etc.)?

 

Dear,

Finally works but ONLY outside of my land, when I am at home (the server is at home) the pop and imap doesn't work. But outside Yes!!

The problem is the dns?? or something similar??

Thanks,

 

Are your server behind NAT Firewall or just regular Firewall?

 

I am behind a Nat, a DMZ. All the port are routed to my server.

More info:

At home:
When I try to enter in my domain (at home) I just see the menu of my router/modem. To enter in the ISPconfig I have to use the private ip (192.168.x.x).

Outside:
All works well.

Thanks,

 

What's the name of the firewall?

For temporary workaround you can allways add domain and ip to hosts file.

sudo nano -w /etc/hosts

add the domain like this (example) :

192.168.0.1 domain.com domain.com

 

I have :

Code:

127.0.0.1       localhost.localdomain   localhost
192.168.1.100   server1.onewayengineering.es    server1

And we can not use the pop/imap at home .... why? I am a little bit desperate, why works out of my house? and at home no. I check all the config file 4 times.

 

Finally solved!!!

With a easy solution I put in my Macbook in /etc/hosts this:

Code:

192.168.1.100   server1.onewayengineering.es

Thanks a lot!!
