mail - detaily pri chybnem odeslani?

Lze nejak zjistit detaily, proc mi nechce odeslat mail funkci mail() ?
Na cz.php.net/mail je jen napsano, ze funkce vraci true/false, coz je dost malo, kdyz mi to nefunguje.

Nastaveno to mam dobre:
hlavicka = From: testmracek@seznam.cz Return-Path: testmracek@seznam.cz Reply-To: testmracek@seznam.cz Content-Type: text/plain; charset=utf-8
to = web@fpf.slu.cz
subj = [#980600] [Fwd: [Fwd: [Fwd: řeky daleké]]]

Jen mi to proste mail neodesle. imap mam v php nainstalovany, mozna na odeslani jeste nekde neco treba.
Program poustim z localhost pod linux Kubuntu (jestli treba neni problem v tom).

Nemam zdani, PC jsem prebral po predchudci, imap jsem doinstalovaval, zkusim se podivat.
Jsem ocekaval, zem i php hodi nejakou chybu, kdyz se mu nepodari odeslat mail.

mimochodem, nasel jsem, ze imap ma vlastni funkci imap_mail(), ale ta se chova trochu odlisne.
Kdezto:
mail (...) - vrati nebyl odeslan, false
imap_send (...) - vrati byl odeslan, true, ale mail mi nedojde

PHP imap_mail() - vraci TRUE
/var/log/apache2
chyba = sh: /usr/sbin/sendmail: not found

PHP mail() - vrati FALSE
a tutez chybu v logu

Takze neco nemam nastaveno, jasny. Co s tim dal?
v /usr/sbin/
neni zadny sendmail

jj, uz jsem provedl pres synaptik, taky napadlo :)
Docela dlouho trvalo.
Ale ted nepise v apache-logu nic, ale pise mail.log
... My unqualified mail host (localhost) - sleeping for retry

pise to funkce mail, jeste zkusim imap_mail()

nas linuxovy technik mi psal, ze treba nekde nastavit SMTP na nas server (aaa.bbb.cc)

uz to mam vyresene

- odinstaloval jsem sendmail, pry je deravy...
- nainstaloval postfix
- zakomentoval vsechny radky v /etc/postfix/main.cf (protoze jsem je nepotreboval)
- pridal nebo pozmenil radky v /etc/postfix/main.cf (aaa.bbb.ccc.cz = smtp server):
myorigin = peter.aaa.bbb.ccc.cz
relayhost = aaa.bbb.ccc.cz
inet.interface = 127.0.0.1
local_transport = error:local delivery is disabled

a mail mi prisel na mailbox na nick@aaa.bbb.ccc.cz
