The "FETCH" command will give you output like:
* 1 FETCH (ENVELOPE ("Mon, 16 Feb 2015 13:50:31 -0500" " OT: Extracting Subject Lines from IMAP Mailbox" (("Tim Evans" NIL "tkevans" "tkevans.com")) ((NIL NIL "centos-bounces" "centos.org")) (("CentOS mailing list" NIL "centos" "centos.org")) (("CentOS mailing list" NIL "centos" "centos.org")) NIL NIL NIL "<54E23BF7.7020009@xxxxxxxxxxx>"))
* 2 FETCH (ENVELOPE ("Mon, 16 Feb 2015 19:33:43 +0000 (GMT)" "Re: OT: Extracting Subject Lines from IMAP Mailbox" (("Nux!" NIL "nux" "li.nux.ro")) ((NIL NIL "centos-bounces" "centos.org")) (("CentOS mailing list" NIL "centos" "centos.org")) (("CentOS mailing list" NIL "centos" "centos.org")) NIL NIL "<54E23BF7.7020009@xxxxxxxxxxx>" "<1705307878.67382.1424115223759.JavaMail.zimbra@xxxxxxxxx>"))
>From RFC 3501 we can be sure of the order of the data:
The fields of the envelope structure are in the following
order: date, subject, from, sender, reply-to, to, cc, bcc,
in-reply-to, and message-id. The date, subject, in-reply-to,
and message-id fields are strings. The from, sender, reply-to,
to, cc, and bcc fields are parenthesized lists of address
structures.
