Dotaz: mailx

[samox86]

ahoj
generujem maily pomocou prikazu mail. V hlavicke doruceneho mailu sa vsak za odosielatela pridava (odosielatel). "From" teda vyzera takto:

michal@domena.tld (michal)

za beznych okolnosti je to vyhoda (client zobrazi ako odosielatela iba obsah zatvorky a hned vidim od koho je). ja vsak pouzivam mail na monitoring a pokial tam bude ta zatvorka neprejde mi to.

otazka znie: ako nastavit mail/postfix aby From obsahovalo iba mailovu adresu???

mailx.x86_64 8.1.1-44.2.2
postfix.x86_64 2:2.3.3-2.1.el5_2
procmail.x86_64 3.22-17.1.el5.centos

Dakujem
samox86

PS: PHP mail() funkcia generuje maily bez "(odosielatel)" v From.

POdle meho hlavicku neresi postak, ale klient ktery postu odesila, takze za to muze mail, nicmene bych si na konfiguroval mutt a odesilal mail presnej i pres prikazovou radku bez problemu. lavicka se definuje kombinaci:

set realname="Joe User"
 set from="user@host"
 set use_from=yes

dakujem za odpoved, vobec ma nenapadlo pouzit mutt :)

na druhej strane set from= sice nastavi odosielatela, nie vsak format. stale sa tam pridava meno usera - akurat v inom formate :D

From: user < user@domena.tld>
To: komu@domena.tld

set use_from povoli/zakaze From ako take (ak je NO tak from je uplne prazdne)

dakujem

ahoj
po marnom hladani "inteligentneho" klienta som dostal napad odoslat mail cez telnet. pri googleni som vsak nasiel nasledovny sposob. script po uprave vyzera takto:

$ echo "konecne to funguje" | ./mailx -s predmet adresat@domena.tld

$ cat mailx
#!/bin/bash
DATA=`echo 0`
SUBJECT=$2
MAILTO=$3

if [[ $1 != "-s" || $2 == "" || $3 == "" || $DATA == "" ]]; then
echo "Usage: mailx -s subject to-addr"
exit 1
fi

#### SEND MAIL via RAW TCP #######
exec 3<>/dev/tcp/localhost/25

if [ $? -ne 0 ] ; then
echo "ERROR: Cannot connect to the Mail Server";
echo "Please check the servername and/or the port number"
exit 2
fi

echo -en "HELO box.sk\r\n" >&3
echo -en "MAIL FROM:uzivatel@box.sk\r\n" >&3
echo -en "RCPT TO:$MAILTO\r\n" >&3
echo -en "DATA\r\n" >&3
echo -en "Subject: $SUBJECT\r\n\r\n" >&3
echo -en "$DATA\r\n" >&3
echo -en ".\r\n" >&3
echo -en "QUIT\r\n" >&3
#cat <&3 # uncomment this line to see the output on the console (for debug)

exit 0
