If I add a custom header to an email (for identifying a specific database record), will this header be removed when someone replies to the message? Does the email program used for replying affect this?

Usually not, especially if the header starts with 'X-'. Most programs preserve those kinds of headers. Quote: Does the email program used for replying affect this? Yes, since the program has to make a copy of the message when replying. If it does not copy all of the headers properly, then you will have to tell the program's author that the replying is faulty.

I am going to test with some X-Headers Quote: Does the email program used for replying affect this? Yes, since the program has to make a copy of the message when replying. If it does not copy all of the headers properly, then you will have to tell the program's author that the replying is faulty. Is there any other "secret" way I can add a simple text field that always gets returned in an email reply? I can't assume the message body will be retained. What I am trying to do is file the email responses in a database and I need some way of identifying the customer and specific ID of a record.

Quote: Is there any other "secret" way I can add a simple text field that always gets returned in an email reply? Some systems put the relevant data into the Subject header, so that the ID is still in the Subject when replying. Others provide a "Reply-To" header that includes the ID as part of the email address where the reply is to be sent (you need custom control over the SMTP server in order to implement this). Quote: I can't assume the message body will be retained. Some systems do require that, and say as much in the body text so users won't delete the required fields.

Further research reveils that many email programs do not preserve custom headers after all, if very rarely. You would be best off sticking with putting your data into the Subject header, or into the return address.

You would be best off sticking with putting your data into the Subject header, or into the return address. I like the idea of using the return address - I never considered that one. Maybe I can use all three methods: return address, coded subject line and then throw inconsistent replies in a mailbox for human review. Thanks for all you help. -Johnnie Back to top Ciaran Costelloe Guest Posted: Sat Jul 15, 2006 5:50 am    Post subject: Re: Do Custom Email Headers Persist for Replies Johnnie Norsworthy wrote: Quote: My software sends emails using Indy.

Thanks, Johnnie Add a References header and In-Reply-To header, they should be preserved (while the replying client may add extra references, it should include your one). That is what they are for.

That is very unfortunate: to me, that means that Outlook does not comply with the RFCs, though I suppose I should not be surprised. It is possible that Outlook is using an X header: send an email to it, and check if the reply has any similar X header (like X-In-Reply-To), then try sending it an email with a similar X header and see if it returns it. Your email program may have to then send those in addition to the standard RFC ones.

I tried this: I added headers: References, In-Reply-To, X-References, X-In-Reply-To They were all received by Outlook 2003, so I know Indy is sending them fine. When replying: All those headers were removed, except In-Reply-To, which was blank on the response. Should the headers be a specific format to be retained? I was just testing with random alpha and number text. -Johnnie Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> Delphi Internet Winsock All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
