Hi,
something must changed in ssl/tls or in postfix. After some time my
postfix log write (spam) this:
postfix/smtpd[75310]: timeout after EHLO from localhost[127.0.0.1]
postfix/smtpd[75273]: timeout after DATA (0 bytes) from localhost[127.0.0.1]
postfix/smtpd[75316]: timeout after MAIL from localhost[127.0.0.1]
postfix/smtpd[75258]: timeout after DATA (0 bytes) from localhost[127.0.0.1]
postfix/smtpd[75284]: timeout after STARTTLS from localhost[127.0.0.1]
I tried everything in assp and in postfix but it is same. I can't use
tls proxy on assp becuse messages will be non readable for assp. I must
tur on 587 submisson at postfix and turn of in assp. This works for
users but for meassages from outside some tls connections are timeouted too.
I am using ubuntu server 20.04 LTS (want use centos 7 but it is
impossible to install recommended perl with packages on it :-))

Yeah, with the Disable SSL setting blank and also with 25 added to the
Force TLS proxy setting incoming connections just time out (unsure if
it's all the time or just most of the time).
Jul-29-21 21:19:31 [Worker_3] [TLS-in] [TLS-out] 209.85.218.52
TLS-Connection idle for 180 secs - timeout
Jul-29-21 21:19:31 [Worker_3] [TLS-in] [TLS-out] 209.85.218.52 [SMTP
Status] 451 Connection timeout, try later
I'll have to test more thoroughly when I have time.

Just my 1 1/2 cents:
I'm not sure why you needed to (or would want to) disable ssl on port
25,
but setting
Disable SSL on listenports: 25
will make it so that outside smtp servers communicate with you without
encryption. Outside centers always deliver on port 25, and won't try
587
or any other port.

I fought with this for quite a while the other day after upgrading my
VPS from Debian 9 to 10.
It seems something must have changed with SSL handling at another
level (maybe something with a Postfix update?).
What I ended up with:
Network Setup:
SMTP Listen Port: 25
SMTP Destination: 125
SMTP Secure Listen Port: 465
SSL Destination: 1465
Second SMTP Listen Port: 587
Second SMTP Destination: 1587
Force SMTP AUTH on Second SMTP Listen Port: On
SSL/TLS:
How to Handle STARTTLS Request: do TLS
Disable SSL on listenports: 25
Force TLS to Proxy on this Ports: 587
Client Side:
Connections to port 465: SSL/TLS
Connections to port 587: STARTTLS
