    Hi Folks, I'm new on HowToForge and almost new on Ubuntu.
    I found here many information to set a AWS server on my own.

    I installed the DKIM patch and it's work great, but now I can't send mails.
    I had already problems sendig mails, but now are deeper.
    Some mails was sent and I tested my DKIM sign, but now I don't know what happend...

    ISPConfig version is 3.0.5.4p9
    Ubuntu 14.04.4 LTS

    Yoy can see mail.log here:
    Code:
    May  1 20:55:17 dingalin postfix/smtpd[3235]: connect from unknown[206.132.109.65]

    May  1 20:55:36 dingalin postfix/smtpd[3235]: disconnect from unknown[206.132.109.65]
    
    I already read many tutorials and forums with the same problem but I still stopped on that.

    Obviously the problem is "warning: connect to transport private/amavis: Connection refused"

    I have the same results from Thunderbird and SquirrelMail.
    The process completed succesfully, without errors, but the e.mail never leaves the queue

    I hope you can help me!
    Thank you very much and best regards from Argentina!

    It looks like you have a mixup in the name of your amavis transport, some places use 'smtp-amavis', while others use just 'amavis'. I'm not familiar with the 3.0.5 DKIM patch, but checking a newer 3.1 box it appears to be consistently named 'amavis'. Try changing your master.cf to that (4 places) and check what /etc/postfix/tag_as_*.re files have set also.

    Thank you very much Jesse.
    What do you suggest?
    I leave everything as is, but change smtp-amavis tu just amavis?

    I have exactly this:
    /^/ FILTER amavis:[127.0.0.1]:10024
     
  7. Jesse Norell

    Jesse Norell Active Member

    Yes, something like:
    Code:
    # cp /etc/postfix/master.cf /etc/postfix/master.cf.bak
    # sed -i 's/smtp-amavis/amavis/g' /etc/postfix/master.cf
    # postfix reload

    Thank you again Jesse, but sadly it doesn't work, but maybe is the right road, because change the errors.

    Now my test e.mails were sent, I do not change anything else!
    But 15 to 20 minutes later.
    In other test the delay was 1 to 3 minutes.
    From webmail (squirrelmail) the delay was minimum.
    Could be the RAM? I have only 1 GB in my EC2 Instance, but 2GB SWAP

    That temporary reject (by the remote server, nothing to do with yours) was probably greylisting employed at the remote end, which would cause a delay on your first email but not subsequent ones. As your message did go through when retrying, you may be good; keep an eye out for any other errors and test things.

    You are my heroe Jesse!
    I ask as last resource because I like to investigate, but here I couldn't.
    Thank you very much again!
