I have an application, which has been running sucessfullt for around 18
months, which accepts files by e-mail and uploads an XML attachment to a DB.
The email client is the Indy POP3 client and the message loaded into an
IDmessage. The .XML attachement is then saved to disk using 'savetofile'
before being processed by my code.
Suddenly, the application has stopped working, and this is due to the
attachment not being decoded by Indy, but saved to disk in MIME format; just
the attachment that is, not the whole file. When I look at the message
source, nothing appears to be obviously wrong, but the sending client's
format has changed a little and I presume that this has caused the problem.
Outlook & outlook express can parse the message and save the file
sucessfully. I was using the version of Indy supplied with Delphi 7. I
have upgraded it to the latest version 9 and the latest 10 (not the
development one). This has had no effect. As there seems to be some debate
about Indy's relyability, I downloaded & tried a set of components calling
themselves the 'clever components', but they were also unable to parse the
message.
Unfortunately this problem is blocking an order processing system, so I
would be greateful if anyone can offer a hint as to a solution. A copy if a
sample message, with confidential elements ***ed out, is shown below.
Many thanks for any assistance,
Mike Hall
