I begin by saying thank you for your tutorials
I made a mail server with your explanation with iredmail on ubuntu and it works at
perfection I have been using it at home for two years I have an ADSL with public ip and therefore everything is ok
then I have another line where I wanted to do a second mail server and where i don’t have public ip so i wanted to do haproxy imap smtp
now I wanted to do haproxy SMTP IMAP and for 15 days I have been trying without success
or better if I use Roundcube it goes both sending and receiving mail to Gmail and other mclinks etc …
but when I try to use thunderbird error cannot contact SMTP server
or saw the log in /var/log/mail.log
using roundcube he makes the connection with localhost [127.0.0.1] Anonymous TLS connection
established from localhost [127.0.0.1]: TLSv1.3 with cipher …
the mail is sent
when i use thunderbird it connects with connect from unknown [10.10.10.1]
SSL_accept error from unknown [10.10.10.1]: -1
warning: TLS library problem: error: 1408F10B: SSL routines: ssl3_get_record: wrong version number: …/ ssl / record / ssl3_reco
and does not send the email
or understood that the problem is the change from localhost 127.0.0.1 to unknown 10.10.10.1
something must be added in / etc / hosts on the hapro server side and on the mail server side
then I wanted to ask you but hostname must be the same both on the haproxy server and on the iredmail server
and finally when you say add a mx record but if one already exists I have to put two and how?
thanks again for existing
LINUX was there, there is and there will be
