Reports of attachment blocking not working as expected

Requested examples of instances where this is occurring in forum threads.

emails with attachments sent to you

I've fixed the issue that if more than one attachment was removed, new attachments stating that the original was removed, was not added to the email. I'm still waiting for examples where the blocking has failed to remove an attachment.

Martin,
I looked at this again and its not working correctly. If I attach two files which are in block list then they get deleted but also the rest of the content in the mail is being deleted. And I'm seeing three .txt attachments created, one for one of the files and two for the other file.
I tried this with eudora and live mail.
It seems to be worse if mail contains various other content such as inline images. I can't actually predict what will and won't appear in received mail but its simple to generate the problem by sending two attachments with some text in mail and an inline image.

I've done some changes to this. Previously the attachment blocker removed all parts of the email and rebuilt it from scratch, excluding the blocked attachments. This gets complicated quickly, with all the different possible variants of inlined images, and so on. I've changed this so that rather than re-writing the entire email, hMailServer updates the existing attachments (with new content and new name). This should hopefully be a much more robust solution. Have run tests using inlined images and other variants (with and without html, multiple attachments where some are allowd) and more.

Fixed in 5.6.
