I'm aware of that and have been following the conversations surrounding this topic.

I didn't intend to suggest that exim should provide a line-wrapping facility. Rather I was referring to your earlier comment from 2016 about the feasibility of handling arbitrary-length lines in DKIM signing. Assuming an exim configuration that does not limit lines to 1000 octets (998 characters), that would allow such "bad" messages through without special attention.

It's been my experience that expecting the source of the messages to be fixed is often impossible even when the programmer is in-house, alive and well and you have face-to-face contact with them. And people will continue to expect the messages to get through.

If exim will not be reworked to sign messages with arbitrary-length lines then I might end up concocting a line-wrapping filter since it seems it could help with at least these two issues mentioned here.
