smtp_accept_max_per_host and sender_host_name

When I try to use $sender_host_name, the first lookup works. All subsequent
lookups return the the same as the first one. I'm guessing the name isn't
cleared in the main process.

Would this be a correct assumption?

I looked at daemon.c handle_smtp_call() at the end. It clears the address
but not name.

Please don't discuss the reasons this shouldn't be done. I'm only
interested in the fact that sender_host_name is not changed after the first
lookup.

Exim version: 4.95-RC2 debian but custom compiled and using custom exim.conf

Yup. This looks like a bug, introduced by a mismerge over four
years ago. Nobody noticed, in all that time....

Since you're compiling your own, just add the obvious line.

I guess noone needs that functionality or they patched it themselves.
I thought that it being used in the main process would have an effect on the
subprocess, but it doesn't appear to.

Next time I decide to compile exim, I'll add it. I'm ok not using
sender_host_name for now.

Thanks for confirming.
