    Hallo I have installed ISPConfig 3.1 on Ubuntu 15.10 64bit server (VPS)
    if I try to send mail to me by a google account google sen me this error:
    "Technical details of temporary failure: The recipient server did not accept our requests to connect"
    "unable to read banner"
    I can check for mail on server.
    So I think my DNS setting and almost IPConfig mail setting is right.

    Can anybody help please?
    my netstat -tulpn:

    some more data:
    I try same command above on 25 port same result but if I try on 587 I get:
    Code:
    leonardo@leon:$ openssl s_client -connect host.domain:587

    To use s_client on port 587 you need to add `-starttls smtp` to your options. Can you post the output in a code block so it preserves formatting? (ie. in this editor, it's the Insert button > Code) Or just post the actual server/domain name you are testing so it can be queried remotely.

    I often use markdown and so I haven't see the button. Sorry.
    My problem is that my postfix cannot receive mail.
    After two days I understood that there is a problem on my self signed certificate.
    so I try some solution on web unless I found https://help.ubuntu.com/community/Postfix
    that help me a lot.
    ... but not enough :eek:
    if look at my fetchmail log:
    Code:
    Segnalato OpenSSL: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Oct  4 18:42:02 server fetchmail[6590]: Questo potrebbe significare che il server non ha fornito il certificato(i) CA intermedio, non c'è niente che fetchmail possa fare al riguardo. Per ulteriori dettagli consultare il documento README.SSL-SERVER fornito con fetchmail.
Oct  4 18:42:02 server fetchmail[6590]: Questo potrebbe significare che il certificato firmato della CA principale non è nel percorso dei certificati attendibili CA, o che è necessario eseguire un c_rehash nella directory dei certificati. Per ulteriori dettagli consultare la pagina di --sslcertpath e --sslcertfile nel manuale.
    I stop testing for today... my brain is smoking :D

    You do not have "submission" enabled in master.cf, which is why port 587 does not work.

    Thak you Jesse I too have noticed the "submission" part. now I have enabled it but I'm thinking the problems are still the certificate.
    I try to build a CA and self signed cretificate but I'm not shure that is working.
    If google send a mail to me this is now the mail log:

    You removed # between the tlsproxy and submission lines which should not be removed. Add the # in front of the linesthatt start with -o between tlsproxy and submission.

    Hi guys
    Recently I have a got a problem receiving encrypted emails.
    the server was running for months but now it has some problems. I would say 70% of receiving emails are not coming through.
    Sending emails - no problem at all.

    Code:
    mail.log
...

    What would that be?
    Any ideals?

    You hijacked thread. If your problem is related to this thread, have you tried the troubleshooting and fixing already described in this thread?

    Well
    It seems like not very good start.
    I have struggling with the problem for some time now with no solution (so far), so I thought that the problem is related to the topic it may help other readers as well.
    Regarding to your question yes I did but it didn't help.
