b4 and lore and '/' in a message id

[Greg KH <gregkh@linuxfoundation.org>]

I've run into problems with a specific user that happens to send patches
out with a '/' in the message id field.

I think this is a valid thing, but b4 and lore don't seem to handle this
very well.

Here's their latest patch:

$ b4 am YTRuXTu/kePBDwAF@user
Looking up https://lore.kernel.org/r/YTRuXTu%2FkePBDwAF%40user
That message-id is not known.

And yes, if you go to the above link, it is not found.

But, if you go to 'all' it is found:
	https://lore.kernel.org/all/YTRuXTu%2FkePBDwAF@user

Any hints on what to do here?

Note, this is the second time this has happened.  First time I wrongly
blamed the developer that they submitted the patch incorrectly, this
time they graciously pointed out that they had sent it correctly,
something was wrong with my side :)

Saurav, how are you sending these patches out, using 'git send-email' or
something else?  What is generating that message id?

thanks,
