* -= README =-
* This is a drop in replacement modification for the Wordpress 1.2 series that enables
* you to send e-mail's with picture and document attachments.
* For more information check out my blog - http://blade.lansmash.com
* This script now has some additional features
* You can include images as part of the text by using the image place holder text. by default this is #img1# #img2# etc
* You can also have your email delay it's publication
*    just add the string delay:XdXhXm  where X is a number d = days , h = hours, m = minutes - you can do any combination
*   so delay:1d1m = 1 day 1 minute
*      delay:15m1h = 1 hour 15 minutes

* -= History =-

* Version 0.312.3-HEY  (2005-05)
* -> Some changes and Bugfixes by Adrian Heydecker
* -> Not (yet) in main development branch.
* Fixed bug: JPEG-thumbnails had a bigger filesize than full images caused by bad hardcoded compression value.
* Fixed bug: If images and signatures were present but no placeholder tags, the images were deleted together with the signature.
* Fixed bug: Generates valid postnames for users of mod_rewrite. Permalinks to posts should now work even when whitespaces are present in the subject line.
* Added support for Quoted Printable encoded mail.
* Added ability to encode Wordpress-posts in charset ISO-8859-1 instead of UTF-8.
* Added ability to choose JPEG-compression value for thumbnails.
* Added ability to add class=”” and style=”” to images.
* Added ability to use a different mailadress (eg. mobile) without setting up a new Wordpress-account.
*
* Version 0.312.2
* BUGFIX: It now removes the delay tag from the message
* Version 0.312.1
* Added modification for placeholder support for images (David Luden)
* Added in support to automatically scale down big images (Dirk Elmendorf)
* Fixed bug with multiple emails all getting the contents of the first image tag (Dirk Elmendorf)
* Added option to allow HTML in the body and subject of the email (Dirk Elmendorf)
* Switch config options to defines to reduce the number of global variables (Dirk Elmendorf)
* Added tests to make sure there is a trailing slash on the DIR definitions (Dirk Elmendorf)
* Add tests to see if they have gd installed (Dirk Elmendorf)
* Seperate the scaling out to a function for easier usage (Dirk Elmendorf)
* Add delay feature for future posting. (Dirk Elmendorf)
* Added in ability to use strtotime if it is available (Dirk ELmendorf)
*
* Todo
*   Have option to have the email that is rejected forwarded on to another address.
* Fix bug that id still diplays the delay tag in the body
* Version 0.312 – 2005-03
* – CHANGE FOR DEFAULT E-mail Categories, instead of [General] Subject you can now use General: Subject in the subject line.  Less typing, and there must be a space after the colon.
* – Fixed bugs with no default posting for categories and user
* Version 0.311 – 2005-01
* – eep, major bug for pop3 server. Next time I test my code more before I released, fixed so that pop3 now works.`
* Version 0.31 – 2004-12 & 2005-01
* (Has it been this long, best get back into the swing of things… did most of this coding on my holiday as I didn’t have a machine to play WoW on :)
* – moved the deletion of pop3 emails into a check so that e-mails aren’t deleted without proper checking.
* – added html ‘decoding’ (basic support for Thunderbird & Outlook)
* – updated the Category search so that it matches words as well as numbers (i.e. [General] Subjectname will work instead of just [1] Subjectname)
* – Changed time function from time to strtotime (as per Senior Pez’s suggestion), but found out that strtotime isn’t in default php distro so removed…
*
* Vesion 0.3 – 2004-09
* – Added UBB decoding support
* – Added default title (when there is no subject assigned)
* – Started doing a little code cleanup, been reading Advanced PHP Book :)
*
* Version 0.2 – 2004-08
* – Stopped using pear body decoding in favour of own decoding (may be slower but more modifiable) because of enriched text decoding
* – Added base64_decode checking (may help mobile phone users)
* – Fixed Subject line for non-english users (htmlentities instead of just trim)
* – Fixed error in some pop hanging -> more graceful exit on event on no emails in inbox ($pop3->quit)
* – Added work around for email addresses with exta <> in field (ie: <blade@lansmash.com> instead of blade@lasmash.com
* – Added some ===basic=== enriched text support
* – Updated readme file for easier install
* – Easy modify of globals (such as PHOTOSDIR and FILESDIR)
* – Cleaned up some pear stuff in install
*
* Version 0.1 – 2004-06
* First release
