How do I send E-Mail from a webclient through ISPconfig?

  1. Hi,
    I would like to know how to set up my online client to send email with ispconfig as the smtp.
    What are the:
    - server
    - port
    - requires secure connection?
    - username
    - password

    Thanks in advance! :)

    Your mail server name.
    Probably 587. If that doesn't work, edit /etc/postfix/ and enable the submission service (refer to a Perfect Server guide).
    The email address you create for this account.
    The password you set for this account.

  3. Thank you a lot.

    I experienced that gmail works like a charm with secured transfer. is a pain and works best if you leave the TLS/SSL box unchecked.

    Sending your mail usernames/passwords over the network in plain text is a common way to have your email accounts abused, you'd be much better off getting SSL/TLS working. I'm not familiar with the specific issues outlook has, but in general make sure your certificate / certificate chain is good, and in your mail client, try using the servername that matches the CN (common name) found in the certificate.
  5. I have no idea how to find out or change what I used in the certificate in question.
    Isn't that a self-signed certificate?

    Please elaborate more on the certificate chain and how to make it work.

    Yes, you probably have a self-signed certificate, which is what the ispconfig installer creates. See for how to use a letsencrypt certificate (the instructions there should actually work for ispconfig 3.0.5 as well, as they only cover setting up the certificate for postfix/dovecot - you can not use letsencrypt for client websites in 3.0.5).

    As that is quite unrelated to the topic in this thread or even the ISPConfig 3 Forum, you might post your question(s) under the general Linux Forum.
