[EdLUG] php/mail forwarding pdf attachment

[Tai Kedzierski]

Hi James

That is unfortunately insufficient information - you haven't specified how
(example code) you are attempting to achieve this to be able to pinpoint
what is going amiss.

- how the email raw data is being retrieved (lib? custom code?)
- how this is being written to the smtp endpoint (lib? custom code?)
- what library is being used for your smtp receiver, and if none, what the
implementation actually does
- whether the code might be mangling data (if a content length is specified
and copied, but your code replaces LF with CRLF , then data could be
falsely truncated)
- whether the code might be mangling data (if your code is reading utf-8
and writing it rejigged into some sort of win-latin-1 or other, then the
data could be mangled)
- what the raw message and attachment look like coming in, and what it
looks like when going back out (byte for byte, using a simple example
attachment)
- whether the code might be failing (have you checked logs? what do they
indicate?)
- many other possibilities no doubt, depending on your implementation of
the solution overall

The above may or may no apply in your case (but worth ruling out each in
turn) ; if there are further details you can share about the
implementation, it may help narrow down the relevant questions to ask.
