Okay. You can run exim with full debug option
# killall exim; exim -d+all -bd
Exim is not detached from terminal in this case and writes debug to standart output( console). In this debug output try to find lines about checking path/domain mailbox/disk quotas and writing message to temp. Delivered mail looks like this
Code:
17:33:54 82169 ensuring maildir directories exist in /home/------/imap/-----.com.ua/terem-ua/Maildir
