Looking for a command-line way to extract only the Subject lines from my mailbox on my ISP's IMAP server, without actually downloading/modifying the contents of the mailbox. Sort of the remote equivalent of locally doing:
$ grep ^Subject /var/spool/mail/mymailbox > subjectlistfile
Thanks.
http://sourceforge.net/projects/imaputils/files/ ?
I guess you'll at least need to download and parse the email headers.

Thanks. Don't see this in the usual repos, but I do see the epel repo has something called "uw-imap-utils," which seem to date to 2007. I'll take a look at both.

I do this sort of thing with Python and its 'imaplib'
Something like this will return a list of all unseen messages in the security folder where Subject contains 'Sec-Blocked'.
import imaplib conn = imaplib.IMAP4('example.com') c, d = conn.login('username', 'password') c, n = conn.select('INBOX.security') c, s = conn.uid('search', None, '(UNSEEN HEADER SUBJECT Sec-Blocked)') msgnumbers = s[0].split() unseenUIDs = set(msgnumbers) # using set for later manipulations for uid in sorted(unseenUIDs) # do something for each uid
# done

telnet (or use openssl) to connect to the imap port.
eg telnet localhost imap a1 LOGIN username password a2 SELECT INBOX a3 FETCH 1:* ENVELOPE a4 logout
The "FETCH" command will give you output like:
* 1 FETCH (ENVELOPE ("Mon, 16 Feb 2015 13:50:31 -0500" "[CentOS] 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@tkevans.com")) * 2 FETCH (ENVELOPE ("Mon, 16 Feb 2015 19:33:43 +0000 (GMT)" "Re: [CentOS] OT: Extracting Subject Lines from IMAP Mailbox" (("Nux!"

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.
