Cannot connect to SMTP through Thunderbird

    Hi!


    On my VPS there is:

    • Ubuntu 16.04.2 LTS
      Release: 16.04
      Codename: xenial
    • i-MSCP 1.4.3
      Build: 20170417
      Codename: Zimmer
    • FQDN: admin.b-web.hu

    I have problem with SMTP. Through Rainloop I can send mails, but when I setup e-mail client to Desktop PC (like Thunderbid) and try to send it's give the error "Cant connect to SMTP - timeout".


    I check the SMTP settings and got this error:


    Code

    And this error when try to send something to other e-mail address:



    Where could be the problem?!


    Thanks in advance!
