I just discovered that there is an `*imap log*' buffer:
=====
23:02:56 16070 APPEND "people.NameSurname" {1922}
23:02:56 16071 EXAMINE "people.NameSurname"
23:02:56 16072 UID SEARCH HEADER Message-Id "<NNNNNNNNNN.fsf@gismo.pca.it>"
23:02:56 16073 SELECT "people.NameSurname"
23:02:56 16074 UID STORE 1196 +FLAGS.SILENT (\Seen)
23:02:56 16075 EXAMINE DOES.NOT.EXIST
23:02:56 16076 APPEND "people.NameSurname" {1888}
23:02:57 16077 UID SEARCH HEADER Message-Id "<NNNNNNNNNN.fsf@gismo.pca.it>"
=====

Thx, bye,
