We have this problem with some mails. I paste here a testmail test. So is this a disabled property in exchange server or an error or do I still miss something?

Also keep in mind servers do not always parse things the same way you would. Many practical client download a subset of the headers rather than rely on envelope. Can you expand on that please Max?

Please give examples of commands used to obtain information in subsets of headers that are not relied on in the envelope. I've not found anything to this effect.

See testsuite if interested. I'd also like to emphasize that this module does not contain IMAP4 client! You will need to employ one from CPAN, there are many. The constructor does most of the work here.

It initializes the hierarchial data structure representing all the message parts and their properties. All the parts on all the levels are represented by IMAP::BodyStructure objects and that enables the uniform access to them. It is a direct implementation of the Composite Design Pattern. Returns the MIME type of the part. Returns the MIME encoding of the part. This is usually one of '7bit', '8bit', 'base64' or 'quoted-printable'.

imap fetch bodystructure

Returns the size of the part in octets. It is NOT the size of the data in the part, which may be encoded as quoted-printable leaving us without an obvious method of calculating the exact size of original data.

imap fetch bodystructure

Returns the content-disposition of the part. One of 'inline' or 'attachment', usually. Defaults to inline, but you should remember that if there IS a disposition but you cannot recognize it than act as if it's 'attachment'. And use case-insensitive comparisons. Returns the charset of the part OR the charset of the first nested part. This looks like a good heuristic really. The standard does not say it should be uppercase, by the way. Without any arguments it returns a list of parts in list context and the number in scalar context.

This does not work with Lotus Notes, it things this response is incorrect. And Lotus Notes is fine with this response. Looks like there is some extra stuff in the response for the new implementation It returns 1 for the number of lines in message but it works anyway. Cheers, Martin Bergljung.

Hi, If we could add a configuration parameter to be able to turn on and off the return of extension data that would be good. I have lots of trial users with Lotus Notes clients so I need to find a solution. I did loads of changes and updates to FetchCommand.

Hi, Turned off extensions in the FetchResponseEncoder. DEBUGjames. It is more stateless and commands are not created for every request for example. I think it is quite important to try and keep it stateless and not create loads of objects all the time. For a couple of reasons, memory consumption and speed. I think the code is more scalable now where each request is basically independent, before it seemed to be more sticky sessions like, or I have misunderstood it:- The APIs have also improved a lot in the new implementation.

Hi, I will try it.

I think it might actually be the mailbox implementation of getMessages that is not returning data correctly. Have to check that all stuff in FetchGroup is returned correctly.

I read somewhere that sometimes, instead of representing strings wrapped in double quotes, IMAP would use curly brackets with string length followed by the actual string without quotes. But the string above doesn't seem to strictly adhere to that there's a single-quote, a comma, and a space after the closing curly bracket, and the string itself is wrapped in single-quotes. When I downloaded the entire email, the header for the message part containing that attachment seemed normal:.

OP: If you want a more detailed or alternative explanation as I guess from your offering a bountyI suggest you paste a small snippet of the raw output into your question. I guess there is probably a way with Python's imaplib to get a full debug transcript of the dialog between your client and the server.

Andy Kubiak Andy Kubiak 6 6 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.The IMAP specification rfc is unclear about the body structure of an email.

Below are some examples with explanations. For each:. The program used for formatting is imapbodystructure. The colors have been added manually to highlight the content parts of the email and the way they are combined: yellow for parts and cyan for their combinations. Such mails are rarely seen nowadays.

Most email client send emails in both text and html. The content is the same, but html also includes formatting. That these two parts are in alternative means that they have the same content, so that the mail client can choose which one to show to the user. The following elements A B C Mails can be sent with images in them. This is obtained by an html part with an associated set of images. The intention is that the user is shown the html part with the image embedded into it in the appropriate place.

The two parts are to be presented together, not alternatively. These parts are not alternative views of the same content, but rather they all contribute to what is to be shown to the user. This is a different form of an email containing text and alternatively html and images. Is a common form, but the way images are associated to the text appear incorrect.

The image is associated to both the text and the html parts, while it should be associated to the html part only. The intention might have been that the image is shown alongside the text of the email even if the text part is presented instead of html. Mails with attachments have this structure. In this particular example, the attachment is a single pdf file, while the text of the mail is in a single html part no text alternative, in this case.

The two parts contain different information and are not supposed to be shown together. A mail may contain an attachment and still offer two alternative representation of its text content.

This is another example of how combinations of parts can nest. As before, attachments are included by a MIXED list that contains both the text of the email and the attachments.

A list may contain a single element. An email comprises various parts such as text, html, images and attachmentscombined in various ways alternative, related, mixed. An invididual part is always represented by a list that begins with its content type:.

IMAP BODYSTRUCTURE: formatted examples

Some components of these lists may be missing, but not the first two ones, which are always strings:. The first parenthesis is the first character of the combination list; the second parenthesis is the first character of the first part. This first part may itself be a combination or an individual part, but in both cases begins with an open parenthesis. All lists that are not combinations start with ".

The elements of a list are numbered 123etc. If the first element is also a list, its elements 1. These sequences are then used to retrieve a single part of an email. Calling imapbodystructure with argument -p shows the number sequence of each part of an email; with -calso the number sequence of combinations is printed. For example, one of the body structures above is printed as:.

The parts of this email are retrived by these sequences. For example, the html part of this mail of number has sequence 1. Was this page useful?It should be noted that if another client has modified any message in the folder, the IMAP server may choose to return information that was not explicitly requested. It is therefore important to be prepared to handle both additional fields on a IMessageSummary for messages that were requested as well as summaries for messages that were not requested at all.
