Issue

Replying to some emails leads to a 500 error.

The PHP log file in this case was:

mod_fcgid: stderr: PHP Fatal error: Uncaught TypeError: strlen(): Argument #1 ($str) must be of type string, array given in /usr/local/share/cypht/modules/core/message_functions.php:

I didn't see anything special about that email.
It was a multipart message, one sender and one receiver, some attachments. Nothing appears to be out of the ordinary.
I did notice that this is the case with ALL emails I receive from that company though.

Here's the header (I've changed the IDs and names, so no secrets are shared here):

@jasonmunro, Correct me if I'm wrong but I'm looking at this issue and it looks like the same issue as https://github.com/jasonmunro/cypht/issues/544, only with the Delivered-To header.

Do you think we need to add an extra foreach loop or imploding the array would work here as well?

In the latter case implode() works as we are just plucking links from the header, however in this case we need a loop. I have not looked at the specific code yet but my guess is the best way to handle it is to type check it, and if it's a string make it an array with a single value, then modify the code to always work with arrays.

Ok, that's a good idea. I'll work on that when I get some time.
