if he is one under many the problem may sits at him
i havent seen this slowness in TB 3.1.9
but in former versions, but that wasnt only in sent folder, it was for
all folders with many mails
also clamav-milter etc slows down a little bit
at my setup, as well as some networking problems sometimes
so the failure can be everywhere
i would recommend test with a fresh tb install with small or no firewall
settings on perhaps same local network with the server
if it "feels" there slow too, then try tune dovecot look top logs etc ,
upgrade memory etc
if not , analyse
the clients setup , what is his internet troughput , is it shared ,
what firewall is he using, what OS, how many accounts , does he share
his conect etc
sorry no time for looking your setup now
