Berbicara langsung dengan server IMAP

Untuk berbicara langsung dengan server IMAP, kita dapat menggunakan program telnet dan konek ke port IMAP (defaultnya 143, tapi dapat berbeda).

$ telnet HOSTNAME_ATAU_IP 143

Lihat artikel ini, Menggunakan program telnet, jika Anda masih belum familiar dengan program telnet.

Sekilas protokol IMAP

Setiap baris request dari klien perlu diprefiks (diawali) dengan sebuah string penanda. Pada contoh-contoh di artikel ini digunakan a001.

Contoh

Login:

$ telnet mail.host.com 143
Trying 1.2.3.4...
Connected to mail.host.com
Escape character is '^]'.
* OK [CAPABILITY IMAP4REV1 LITERAL+ SASL-IR LOGIN-REFERRALS AUTH=LOGIN] mail.host.com IMAP4rev1 2004.350 at Fri, 16 Mar 2007 13:51:21 -0500 (CDT)
a01 LOGIN someuser somepass
RESPONSE: a001 OK User logged in

Mengetahui capability IMAP service:

a001 CAPABILITY
* CAPABILITY IMAP4REV1 LITERAL+ IDLE NAMESPACE MAILBOX-REFERRALS BINARY UNSELECT SCAN SORT THREAD=REFERENCES THREAD=ORDEREDSUBJECT MULTIAPPEND SASL-IR LOGIN-REFERRALS AUTH=LOGIN
a001 OK CAPABILITY completed

Logout:

a001 LOGOUT
* BYE mail.host.com IMAP4rev1 server terminating connection
a002 OK LOGOUT completed
Connection closed by foreign host.

Melihat daftar mailbox yang ada (pada contoh, semua anak Inbox):

a001 LIST "Inbox" "*"
* LIST (\HasNoChildren) "." "INBOX.omail.log.old"
* LIST (\HasChildren) "." "INBOX.omail.log"
* LIST (\HasNoChildren) "." "INBOX.Trash"
* LIST (\HasNoChildren) "." "INBOX.Spam"
* LIST (\HasNoChildren) "." "INBOX.Sent"
* LIST (\HasNoChildren) "." "INBOX.Drafts"
* LIST (\Noselect \HasChildren) "." "INBOX.omail"
a001 OK LIST completed

Men-select sebuah mailbox (pada contoh, bernama INBOX):

a001 SELECT INBOX
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen)
* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen \*)]
* 1242 EXISTS
* 0 RECENT
* OK [UIDVALIDITY 1062186210]
* OK [UIDNEXT 1246]
a03 OK [READ-WRITE] Completed

Mendaftar semua message yang ada pada sebuah mailbox yang sedang di-select:

a001 FETCH 1:* FLAGS
* 1 FETCH (FLAGS (\Seen))
* 2 FETCH (FLAGS (\Seen))
* 3 FETCH (FLAGS (\Seen))
* 4 FETCH (FLAGS (\Seen))
* 5 FETCH (FLAGS (\Seen))
* 6 FETCH (FLAGS (\Seen \Answered))
...
a001 OK FETCH completed

Mengambil header-header sebuah message (pada contoh, urutan pertama dan mengambil full headers).

a001 FETCH 1 full
* 1 FETCH (FLAGS (\Seen) INTERNALDATE "15-Mar-2000 13:10:14 -0500" RFC822.SIZE 1
553 ENVELOPE ("Wed, 15 Mar 2007 13:10:11 -0600" "Perl Stuff" (("Rusty Nejdl" NIL
"rnejdl" "verio.net")) (("Rusty Nejdl" NIL "rnejdl" "verio.net")) (("Rusty Nejd

"verio.net")) NIL NIL "<20000315131011.A5381@tethys.ringofsaturn.com>") BODY ("
TEXT" "PLAIN" ("CHARSET" "us-ascii") NIL NIL "7BIT" 359 9))
a001 OK FETCH completed

Mengambil bodi message:

a001 FETCH 1 body[text]

Set quota:

a001 SETQUOTA "" (STORAGE 512)

Get quota:

a001 GETQUOTA ""
* QUOTA "" (STORAGE 10 512)
a001 OK Getquota completed

Get quota root:

a001 GETQUOTAROOT "Inbox"
