That is what I was not sure. I did not know what information was possible available. I was thinking or hoping something same as http logs

My dovecot 2 installation logs this information. E.g.

Jul 26 07:13:02 server dovecot: imap(user): ID sent: name=iPad
	Mail, version=11D201, os=iOS, os-version=7.1.1 (11D201)
Jul 26 07:13:38 server dovecot: imap-login: ID sent:
	name=com.google.android.email, os=android, os-version=4.4.4;
	KTU84P, vendor=LGE, x-android-device-model=Nexus 4,
	x-android-mobile-net-operator=Koodo, AGUID=...: user=<>,
	rip={client-ip}, lip={server-ip}, TLS, session=<BH7SSxn/CQBFrJG2>

If you want this info, upgrade, as a later poster suggests.
