Unable to send email..
I followed the guide for "the perfect server ubuntu 11.10"

The system runs great with 1 small issue.. and it could be a user issue :)

I set up a user account to send/receive email. I then set up thunderbird to send/recv I am able to receive the email fine, but sending it gives error that it times out. So my question is... what port is this guide using and what type of authentication should I be using?

not sure if this helps..

pwcheck_method: saslauthd
mech_list: plain login
allow_plaintext: true
auxprop_plugin: mysql
sql_user: ispconfig
sql_passwd: [omitted]
sql_database: dbispconfig
sql_select: select password from mail_user where login = '%u'

more info.

running 'nmap -v localhost'

resulted in

25/tcp open smtp

So I updated thunderbird to reflect port 25, none for connection security, and authentication method is set to password, transmitted insecurely.

I then try to send an email and I get the mail server has timed out..

any advice? or what should i look at next?

Are there any errors in your mail log (in the /var/log/ directory)?

joey3002 7th June 2012 03:38

no, nothing in the log file. Its almost as if its not hitting the server.

Can you use the server's IP address in Thunderbird instead of a hostname? My guess is that the hostname is pointing to another server.

joey3002 8th June 2012 01:36

no, thats not the issue. I have even made a new server following your v12 guide and same issue. Can you share with me the settings to send email using say thunderbird?

Here's a guide I wrote for my customers (but it's in German):

joey3002 9th June 2012 18:10

thanks, followed the guide you just linked to perfectly but it still times out trying to send email. Receiving is fine, but outgoing times out. How can I verify that I should be using port 25 and that its open?

Please post the outputs of

netstat -tap

iptables -L
Also check your mail log (in the /var/log/ directory) for errors.
