Thank you very much for taking care of this obsolete version and
a clueless user!

~$ uname -a
Linux komensky 2.4.20 #2 Ne kvě 18 18:08:31 EDT 2003 i586 unknown
~$ hostname -f
komensky.volny.cz
~$

And no, I have not set primary_hostname, because this is notebook and it
is often connected to the Internet with different ISP provider and thus
it is in different domain. Do I have to set the variable? If the worst
comes to worst I can do something like

primary_hostname=${lookup{domain}lsearch{/etc/exim/domainlist}{$value}}

and then set the value of domain in /etc/exim/domainlist.

Or is it possible to parse /etc/hosts with exim? I have this as a first
line of the file, is it possible somehow to parse it?

   127.0.0.1      komensky.volny.cz komensky    localhost


Something like

primary_hostname=${sg${lookup{127.0.0.1}lsearch{/etc/hosts}{$value}}\
{^(\S+)\s*(\S+)\s*(\S+)\s*\$}{$1}}

(unfortunately, this one doesn't work; why?)

It would be nice to maintain only one file. Or if I can get output of
'hostname -f' into that variable (but it is not possible to do it in v.
3, is it?).

Yes, that's it. Thanks! Do you think, that any of the suggested ways
could work?

Thanks,
