Re: [twsocket] Decoding MIME messages
Francois,
I'm trying to write a very basic automation, which should try to detect some
patterns within mails, and if a mail content matches, it should save that mail
for further processing and delete it from the pop3 server. Each unprocessed
('unknown' content) should stay on the server, until there's a handler for that
unknown pattern.
In other words, it should be a system where rules/patterns are added as soon as
they're needed.
What I've done so far is using a TPop3Cli component to read mails (in the first
step without deleting from server) and a TMimeDecodeW component to get the
contents. What's to do next is to separate readable (textual) parts of the mail
and ignore all inlines or attachments.
I don't need full code, but a step by step guideline on how to accomplish it.
Currently I'm trying to use TMimeDecodeEx, which seems toi do what I need.
Michael

What I basically need is to extract a text part from each mail, regardless
how many contents it may have.
The text part is not well defined. You may have an HTML message which is
not trivial to convert to a text file. Rendered on screen by a HTML rendere,
it may looks like plain text but actually it isn't. You may also have an RTF
formatted message. Or a plain text part and a HTML part with eauivalent
content. You have to handle all the situation by detecting what format it
is. You are helped by the various headers.
Are you writing an email client, that is a program whose goal is to display
messages on screen ? Then you need ICS-POP3 component to retieve the
messages, ICS MIME component to extract the parts and as many renderer
component as you want to support messages types.
Are you writing some sort of automation which uses email as transport and
use the data within email for data processing and not to display it on
screen as an email ? That's a different thing.

Some mailservers seem to return the original mail completely, including all original attachments. But those aren't of any interest ;) Ok, then just exclude text attachments from being parsed (disposition attachment at least). There are text/plain, text/html and even text/rtf parts though I guess most servers reply text/plain with 7-bit ASCII encoding. The program is meant to act as a feed for a database containing some mail addresses, and does some action there (delete mail addresses which don't exist, put a note on mail addresses where the mailbox is full, and the like). But the most difficult job would be to determine which failure is described where and how, in each reply That's true, since there are probably as many different replies possible as mail servers exist. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Future plans of ICS
I have a couple of questions about future of ICS. 1) FPC port. Will it continue someday? Or maybe just Linux support (according to Emb's roadmap to bring something like Kylix to life someday)? 2) Parse listings in FTP client. I do not ask for parsing implementation (as I understood, you don't feel doing it), but a kind of general workaround, like OnParse event, internal getting listing to TStringList, and so on. Think it would be helpful and not dealing with not standartized things which you don't like. -- Regards, Anton -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

2) Parse listings in FTP client. I do not ask for parsing implementation (as I understood, you don't feel doing it) Full FTP parsing is implemented in TMagFtp, which is a high level version of TFtpClient, you can use the entire unit or borrow TMagFtp.UnpackFtpFDir (which has a lot of dependencies). http://www.magsys.co.uk/delphi/magxfer.asp Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Future plans of ICS
Angus, I know and have already looked into the code, and even tryed to understand it :) But as you've mentioned it's not trivial to grab parsing code out of the component because of lots custom routines used. And I'm talking of slightly another thing: a standard and native ICS interface for parsing. For instance: ftp.Feat() // get feats, determine whether server supports MLST, or MDTM, or anything related ... ftp.GetListing(RemoteDir) - ftp.List(RemoteDir) - get listing into ListingStream - convert it to ListingStringList - invoke OnFtpListingParse not very hard as I see it, but make it easy for others to implement parsing function. But of course, merging Magenta's parsing into ICS would be much more helpful and useful. Full FTP parsing is implemented in TMagFtp, which is a high level version of TFtpClient, you can use the entire unit or borrow TMagFtp.UnpackFtpFDir (which has a lot of dependencies). -- Anton -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Future plans of ICS
I have a couple of questions about future of ICS. 1) FPC port. Will it continue someday? Actually, I never made anything for FPC support, except accepting changes from some developpers to help using ICS in FPC. Or maybe just Linux support (according to Emb's roadmap to bring something like Kylix to life someday)? I had invested a lot in the linux version with exactly not return on investment. As you said, it looks like Embarcadero will some time in the future have a Linux version. This time I will invest it only if I have some expected result (read: if I get paid for updating the latest ICS to whatever will the Delphi for Linux be). 2) Parse listings in FTP client. I think FTP component is about transport, including transporting a file list. Parsing a file list should - imo - implemented in another component. This is similar to what I've done with POP3 and MIME decode components.

[twsocket] libeay32.dll issue

2) I see your point in this too, but you could add some helping thigs like those I suggested, aren't you? I don't think anything special is required. Once you get the file list, as any other file, you just submit it to your decoding class.
