Sorry about that. The manager of our list server is investigating
(again). Let's hope it gets sorted this time. (The problem is in moving
the list from the machine where they are edited to the one that actually
does the expansion.) I'll have to send another test message, I suppose.
Caution is clearly the watchword. Meanwhile, here is some stuff you have
missed, the first of which is somewhat ironic:

I am now able to update the list again, and have added the outstanding

I'd be grateful if recipients of this message could please send me a
brief ACK so that I know it is now working correctly.

I've already got a note to worry about -gdbm for HP-UX, and asked for
advice from the list, since I have no access to HP-UX. Does anybody on
the list disagree with Neal? If not, I will make his suggested change in
the next release.

Here's some more random proposals:
1) Support for gdbm and db. The problem with gdbm and db occurs when
we try to get them to emulate ndbm. Then the biggest problem is
that we have to be *sure* to include the correct ndbm.h header.
Note that there is no standard for where db installs it, and gdbm
doesn't install it by default at all.
If we want to support gdbm and/or db, we should do so directly,
not via emulation. Then there will be no conflicts. Shall I
contribute some code?
2) Interprocess communication between eximon and exim is via execing
exim with various switches. How about a socket interface?

I'll certainly look at it, but possibly not very soon. This week is
almost gone; next two weeks I'm rather busy, and then I'm away for 3
weeks...

Er, it isn't interprocess communication, really. If you are suggesting
that the daemon sits there listening on some other port for a connection
from eximon then
(a) all it could usefully do is fork a copy of itself and exec with
the appropriate arguments, so what does this gain over doing that
directly?
(b) how is the security to be maintained?
(c) not everybody runs the daemon.

I would suggest just supporting db, and either include a copy from
4.4bsd-lite (the copyright should allow this), or just tell people where
to find it.... db is faster than even recent gdbm's, and probably more
reliable too....

Hmm... Wouldn't this vasly change the paradigm of operation to one of a
client/server model, perhaps more like zmailer? [If it didn't, then why
bother?]

Thanks for local_domains_include_host. How just one more thing is
preventing us from sharing configure files across machines. Around
here we have set the hostnames without the FQDN. For example, uname
on this machine says 'neal' instead of 'neal.ctd.comsat.com'. So I
can't share the configure, even with local_domains_include_host,
because I need to set primary_name (at least, I think I do). How
about qualify_primary_hostname boolean, or is it unnecessary?

Sounds good. Either automatic as you describe using DNS, or even a
boolean set manually.

Ideas noted. It will be easy enough to do a DNS lookup if the primary
host name contains no dot. It would also be easy to force such a lookup
with a boolean. I suppose for completeness one should also have
qualify_primary_hostname = "string"
to set the qualification explicitly. The only problem with this at the
moment is my time, so please be patient...

Be wary of Gdbm. The standard GNU version only allows the gbm file to be
opened read/write and only allows one writer at a time. So you end up with
only one user at a time, unless you are carefull with ownerships. Hit some
wierd problems with PP's tables under GDBM. Ended up with a lock outside of
gdbm that prevented two processes accessing the db at the same time.

Might be nice to allow across nets...
