IMAPcopy is a tool written by Armin Diehl. Its purpose is to copy emails from one IMAP server to another (or from one IMAP account to another) including the folder hierarchy and even the read status. It’s a command line program written in Delphi and fpc.

Since I am currently migrating a mail server I had use for such a tool and this one was the only one that did not require Java or dotNET, so I tried it. Of course, being a software developer, I found it lacking and improved it.

So, what did I improve?

Mostly one part: I did not like the fact that I had to specify the passwords of the IMAP accounts in the configuration file, so I added an option to specify “?” as the password and the tool would then let me input it at run time. I also added colouring to the the output, so it is easier to spot warnings and errors. And last but not least, I fixed a few typos in the messages.

It’s GPL code, so I’m required to give the source code to everybody to whom I give the executable. I could, of course, simply use the improved version and not tell anybody about it, so I could keep the source code “secret”, but on the other hand, why should I?

So, here is the source code. It compiles with Delphi 2007, I have not tested any other versions and I am sure it won’t compile with fpc (yes, that’s no improvement, but I don’t care).

It also needs a a Delphi port of the Borland CRT unit. I used the one released 1998 by Sergey Perevoznik, which is NOT licensed under the GPL. I have no idea where I got it from and I am not sure about the copyright since it looks like it started out as a copy of Borland’s source code. So I am not going to provide it here, sorry. But you might have a look at Embarcadero’s CodeCentral for alternatives.

Sorry, the comment form is closed at this time.
