The mailbox transport I use is a pipe to an MDA that treats the username case-sensitively, so I have given the "u" flag in the transport, but I also have
recipient_delimiter = +
and the address extensions are being downcased as well.
Does postfix offer a better solution, will it, or is this the wrong
approach?
I can hack the MDA to make it case-insensitive if that's the most
appropriate way to fix this.
Thanks,
