Looks like you have no root CAs installed in your system.

Typically 30-60s delays are due to waits for DNS responses. Check your DNS
environment: contents of /etc/resolv.conf, name servers operation, etc.

You can also run "strace -Tfp <exim_daemon_pid>" to look which syscalls
lead to those delays.
