I've had the following appear in my logfile, and am just wondering what the warning means?

dovecot: managesieve-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [a.b.c.d] dovecot: imap-login: Warning: SSL alert: where=0x4004, ret=256: warning close notify [w.x.y.z]

Should I be worrying about these kinds of messages?

No. They are normal. Since this gets asked a bit too often, changing it to a debug message should help I hope: http://hg.dovecot.org/dovecot-2.2/rev/2714f51e2355

Anyway, you probably shouldn't be using verbose_ssl=yes unless you're actually debugging some SSL issues (I guess the setting should have really been named ssl_debug=yes).
