[Exim] Exim 4.34 VS 3.16

I still have the problem - exim works some hours, but it then refuses to accept
anything but manual tests writing mails to port 25, and the -bh option does not
reveal errors..

pls find below the most active of my configure file.
the filter is unchanged from version 3.16
the server is only used to receive mail for all the domains

the exim recieves mail from a smtp AV scanner 195.192.90.31 (smaug)
the exim_mainlog complains about a localhost.localdomain, but it does not seem
to help to insert it, and the newly installed linux 8 is not being very helpful

mail now bounces giving a unreachable or down from smaug

i am goving away a few days - be back monday

pls. close to revert to 3.16
