   It works. Thanks you.

   Although the malformed mbox I sent is consists of 2 messages, Dovecot 
recognizes 3 messages.

     +OK Dovecot ready.
     user xxxxxxxx
     +OK
     pass xxxxxxxx
     +OK Logged in.
     list
     +OK 3 messages:
     1 23
     2 940
     3 968
     .
     retr 1
     +OK 23 octets
     X-UIDL: i[f"!$h*!!S67!!/RW!!
     .


   In the above pop3 session, message #1 and #2 is originally one 
message, so Dovecot should recognize that the whole mbox contains 2 
messages, not 3 messages.

   I would like you to consider improving Dovecot to skip second (and 
duplicated, unnecessary) "From" separator.
