I am writing you regarding the IMAP API and in particular the FETCH
command.
According to the curl_easy_setopt documentation a FETCH request
is made with the URL
imap://user:[email protected]/INBOX/;UID=1
However, even though in the URL we set a UID the command issued is
FETCH 1 and not UID FETCH 1 which is inconsistent with the rfc3501.
Unfortunately you are correct. Curl doen't implement the UID based commands
at present. The IMAP protocol is still work-in-progress to a certain degree
as I believe we have very few users* of and the current implementation is
only a year old.
Are the UID variants preferred over the non UID versions?
Ah, although it seems inconsistent at first the rfc5092 does allow a
standard FETCH in this case, my bad, quoting the rfc
The <iuid> refers to an IMAP4 message Unique Identifier (UID), and it
SHOULD be used as the <set> argument to the IMAP4 "UID FETCH"
command.
I then tried to make a UID FETCH request through a
CURLOPT_CUSTOMREQUEST. However, the response handler for
custom requests (see imap.c:imap_state_list_resp) cannot handle
the case where the response returns continuation data. For
example the custom request
Currently all custom requests for IMAP overload the behaviour of a LIST
command :(
If i wanted to fix this how would i go about it? I am not yet familiar
enough with the code.
Whilst the URL handling in curl is based of RFC-5092 it doesn't implement it
100% at the moment. For example:
* SEARCH command is via custom command at not URL query parameter
* Doesn't support the <ipartial> keyword
* Doesn't support <enc_mailbox> for EXAMINE custom request
These are things that I would like to change so if you have any suggestions
or ideas about how we may do this or fancy helping out with some patches
that would be fantastic.
Studying this issue, i also noticed that curl implements the FETCH
request as
FETCH n BODY[...]
while the rfc5092 requires a BODY.PEEK, in detail
The <isection> field is optional. If not present, the URL refers to
the entire Internet message as returned by the IMAP command "UID
FETCH <uid> BODY.PEEK[]". If present, the URL refers to the object
returned by a "UID FETCH <uid> BODY.PEEK[<section>]" command.
I am more than happy to help.
Kind regards,
