in your HTML mails)- fix a weird typo for BCC fields- add Content-ID, by alejandro Castro- fix "_" characters in subject, regression fix.- cleanups all around, by Paul Vernon.- SMTP example updated to cope with html emails.**warning** from this version, the html part of mails will not be stored as attachments by default, if you want this behavior, you just do something like: aSakMsg := TSakMsg.Create( self); aSakMsg.HTMLAsAttachment := true; ...3.7.1- fix TSakMsg.PopulateList (Jalin)3.7.2 (codenamed "melissa")- fixed a bug when the Populatelist procedure got re-written in sakMsg. It wasn‘t populating the SendTo field if there was only one e-mail address... (Paul Vernon)3.7.3 - Congratulations to Sergio on the addition to his family. This release was made by Paul Vernon who has temporarily taken over the release functions for the SakMail components whilst Sergio spends time AFK!- The 3.7.2 bug fix added blank entries to the address lists. The PopulateList procedure has been re-written again to hopefully cope with any type of e-mail address formatting.- The SMTP example noted in 3.7.0 actually shipped with this release!3.7.4- Bugfix for detecting UUEncoded mails correctly. Previous versions processed MIME mails with the value ‘begin xyz‘ if it appeared at the beginning of a line as a UUEncoded mail when they should not have.- POP and SMTP connect procedures are now functions. Existing code is unaffected. However, you can now use the following code if (sakPOP.Connect) then begin end;- POP gracefully quits if it receives an error now by calling Disconnect correctly.3.7.5- Further code to improve identification of UUEncoded mails. Essentially looking for the end as well as the beginning to ensure that it is correct.- Code optimisation of certain UUEncoded mail id functions.- Fix to ensure that the body of a mail that is UUEncoded is not lost.- MIME-Version string introduced into TsakMsg component to help with UUEncoded mail identification.- SizeInBytes property altered to read private variable using a function. If the private variable is 0, the function reads the length of the FRawMail.Text property.- Fix to make sure that the filename is not overwritten by a blank value when parsing mail-headers.3.7.6- Fixed list index out of bounds error.- Added POP3 RSET call TSakPOP.Reset.3.7.7- Altered SizeInBytes and Octets values to return server-side size when d/l headers only and use actual size once the entire message is downloaded.- Fixed a bug in GetBasicHeaders where To and CC fields could be mishandled if the mail headers were formed in a particular way.4.0.0 beta- All methods are now wrapped in classes. sak_util is now included for backwards compatibility only.- Several changes to make sakMail thread safe including the introduction of Mutexes which are cross process safe. Critical sections were an option however, although mutexes are a little slower, they are much more effective when you aren‘t sure how the code is going to be deployed...- Made several changes to the way connections are tracked, now making better use of the underlying Delphi components own properties and functions.- Several bug fixes included from solutions posted on mailing lists. Including change to datetime function to respect local time separator. There are more including one that Adem re-raised.- Removed almost all pointers as per Adems suggestion. Makes for neater code.- Hopefully backwards compatibility is kept. This is one of the objectives of the excersice although, internally, the components no longer use any of the non-object based methods. Also some of the non-object based methods actually have been re-written to create an object use the instance of the original method and then destroy the object again. This introduces a minor overhead however, because the objects are discreet, the trade is for much better memory usage and greater thread safety.- Introduced an include file to define compiler directives. Currently there are two directives. One defines whether to use the VCL or not, the other defines whether or not to use the FastStrings components. - With the intoduction of the Include file, this allows the development of code that is optional for users. One of these such changed is the use of the FastStrings base64 decoder. If you install the FastStrings components and turn on the compiler directive, you should have no functional changes however, the base64 decoder routines should have a much higher performance rating. Tests clock in at over 2000% faster attachment decoding on a P4 1.8GHz machine. (1.2Mb file 1686mS native sak Base64 Decoder, 79mS using FastStrings!)- This version is being released as a beta as the changes are pretty drastic. If the code is deemed to be stable and backwards compatible then it will be re-released as v4.0.1 with no changes.4.0.1 beta- Fixed an issue where Range Checking highlighted that the Attachment b64 decode routine raise a Range Error if the line that was to be decoded was empty. i.e. ‘‘.- Introduced a compiler directive to turn off range checking in the sakMIME procedure TBase64DecodingStream.Write to make sure that it runs correctly as Range Checking causes issues in this function.4.0.2 beta- Changed MailDateToDateTime function to the one provided by DengZhaoHui with a few modifications as even though it has better date processing than the original it caused EConvertErrors with some non-rfc dates.- Added the compiler directive to allow the inclusion of MD5 components from the DCPCrypt suite of encryption components. This allows the components to do APOP and SMTP AUTH functions as specified in RFCs 2095, 2104, 2449 and 2554. {UseDCP} ***** NOTE: These functions are experimental as although they are RFC compliant, they have not been tested against a secure mail server yet... *****- Using EurekaLog during load testing of the POP mail component, found and fixed several AV‘s in sakMSG, sakMIME and sakPOP. Mainly simple mistakes that required re-ordering of code or more checks before trying to manipulate data.- Altered the sockets code to be more stable with some servers. The previous implementation was totally incompatible with SendMail NT v3.0.2.- Fix added to compensate for incorrect operation of Connected property in some versions of Delphi.- Altered GetMultiLineFieldBody as per Adems suggestion. Also took some of Adems code and added it to GetFieldValueFromLine as the escape characters can appear in single line headers as well as multi-line ones.- TClientSocket is deprecated in Delphi 7. This may be the next large change in the sakEmail components. - Updated distribution to include more RFC‘s regarding the message format, POP and IMAP and hashing functions for CRAM mechanisms.- Fixed the handling of redirected mails as created by Eudora.- Force PopulateList to clear the list before populating it again.- Created a Delphi 6 package file.4.0.3 - Fixed AUTHSMTP buffer initialisation error. (Dmitry G. Kozhinov and Gabi Slonto)- Improved identification of servers that do not support the UIDL command. A small overhead is intorduced on servers that do support the command and have several mails to download but the feature allows better interaction with those servers that do not support UIDL.- Priority is now reported correctly when an e-mail is being decoded rather than only being used when sending an e-mail.4.0.4- Fixed an issue with a malformed header in a mail sent from MS Word through an Exchange server- Added a couple of try...finally blocks to the sakIMAP component.- Altered the sakIMAP components connected function to mirror the more accurate sakPOP method.- Consolidated all compiler directives into sakDef.inc- Added versioning compiler directives to allow the compilation of sakemail under Delphi 4.- General tidying of code. 4.0.5- Created a Delphi 7 package- Added properties to the IMAP component to allow read access to the LocalAddr and LocalHost socket properties.- Bugfix to sakMsg PopulateList function where a comma separated list did not contain any spaces- Access violation in sakPOP component due to incorrect use of free,freeandnil and compiler directives4.0.6- Added several features to the IMAP components.- Tidied up SMTP authentication routines (Improved use of MD5 for authentication using DCP components)- Included capability to send messages without an SMTP server (using Indy DNS components for MX lookups)- Bugfix in message parsing to stop a recursion loop due to a malformed mail.4.0.7- Memory leaks found by Amos and Paul regarding the sakMsg and sakPOP units respectively.- Bug fixes to attachment save code including stripping out invalid .. sequences from filenames- Improved the GetConnectedState method to check against the RemoteHost value on the Socket.- Updated POP example to be more responsive when downloading mail. Fixed a memory leak.Don‘t forget to subscribe to the mailing list (see the web pages at http://groups.yahoo.com/group/sakemail/)

用启动盘启动，再把别人机器上的user32.dll，拷贝覆盖！

这是非法操作，你肯定应用了空对象
例如
当Form2=nil得时候，
你执行Form2.Caption:='';肯定会引起这样得错误
