Mail Transport Unavailable ?

Hello,

I have setup an inbox on my installation of ISP Config 3. I sent an email to the user that I created. I think looked at the "mail queue" portion of ISP Config 3, and this is what I found:

1101D5C6EC 447 Wed Dec 8 10:48:51 source_name@source_domain.com
(mail transport unavailable)
destination_name@destination_domain.com

Can someone provide some insight into how I can fix this? Thanks!

 

I believe that this may also be relevant...

In the Mail Warn-Log, I see this:

Dec 8 06:05:01 qastudy postfix/smtpd[24703]: warning: ::1: address not listed for hostname localhost
Dec 8 06:08:46 qastudy postfix/qmgr[3316]: warning: connect to transport amavis: No such file or directory

 

This is fixed. Notes for other users:

Please be sure you update your apt sources list as mentioned in the installation instructions. I failed to do that, and my version of maildrop was wrong.

Also, your postfix master.cf should reference "amavis", NOT "smtp-amavis"
