Hello,
I have installed Mailcow on a vsp server. I have no problems so far, but I can’t send or receive mails to certain providers.
The postifix contains the following error:
disconnect from mailhost.domain.de[ip] ehlo=2 starttls=1 mail=1 rcpt=1 data=1 quit=1 commands=7
I have configured mta-sts and tls. But I do not get the error recoverable.
Also, when I send mails, I get the error message:
For further assistance, please send mail to postmaster.
If you do, please attach this problem report. You can
delete your own text from the attached feedback.
