configure pop3 email client on ubuntu 12.04 lts

[speedygarth]

hi there i would be grateful ifi could get help with setting up my thunderbird pop3 email account settings. i have specified my pop3 settings for the incoming and outgoing server with my workplace pop3 mail server settings but it gives me an error message about the smtp mail server setings being incorrect.

Don't suppose you have the email account elsewhere, that you could open the account properties, or access to your work IT support ?

Have a look in Thunderbird > Account Settings > Server Settings > Security Settings and try the different options.

Hi,

Can you post the exact message that you receive please? Your authentication options must match the mail server you are connecting to... Also, make sure your release of Ubuntu is up-to-date

To update - Open the terminal

sudo apt-get update && sudo apt-get upgrade

--Zu

Hi this is the message i recieved:

Sending of message failed.
An error occurred sending mail: SMTP server mail.petrahigh.co.zw is unknown. The server may be incorrectly configured. Please verify that your SMTP server settings are correct and try again.

i have checked my settings with a windows machine and they are the same, i ran the "sudo upgrade" but its still not sending or recieving my emails.
please help!

SMTP server mail.petrahigh.co.zw is unknown

Sounds like a DNS problem to me. Open a terminal type "ping mail.petrahigh.co.zw". Does that work, or does it say "mail.petrahigh.co.zw" is unknown?

thanks for the reply, i pinged the email server and i got an "unknown host" via the terminal.

If you can't resolve the server's name, you probably cannot resolve anything else. Can you ping "www.google.com" or browse the web?

I can resolve the server's hostname from out here on the Internet.

mail.petrahigh.co.zw has address 79.170.44.54

i can browse the web and see my network, but the emails are the problem

I can connect to the POP3 port (110) but not to the SMTP port 25. An nmap scan says that it is filtered:

My guess is that you can only connect to the SMTP port from specific IP addresses. Have you discussed this problem with the administrator of the server?

I get the below with an nmap scan. Is someone working on the server?

Are you trying to configure your mail client inside your network or form the internet? Also, can you post the contents of:

gedit /etc/resolv.conf
