Hello,
After update to 4.94 I have a problem to send emails to google. It
stucks after bdat command For me it looks very simillar to this bug:
https://bugs.exim.org/show_bug.cgi?id=1974
When I tried to send same message using 4.92.3 binaries then message is
correctly received by google. With 4.94 i got:
SMTP<< 220 mx.google.com ESMTP t18si12300997ejj.437 - gsmtp
SMTP>> EHLO **DELETED**
SMTP<< 250-mx.google.com at your service, [**DELETED**]

SMTP<< 250 2.0.0 OK t18si12300997ejj.437 - gsmtp
SMTP>> BDAT 143035 LAST
and after few minutes I received:
SMTP(Connection timed out)<<
LOG: MAIN
H=alt1.gmail-smtp-in.l.google.com [142.250.147.26]: SMTP timeout after
end of data (150824 bytes written): Connection timed out

When I added ``` hosts_try_chunking = ``` to my smtp configuration
then message stucks after:
SMTP>> STARTTLS

SMTP<< 354 Go ahead k22si16455243wmr.170 - gsmtp

any idea what can cause this and why using 4.92.3 exim it works and
using 4.94 it doesn't?
