Hi again,

Now I have it and still does not work.

echo "Test Message" | sendmail user@domain.com -f user@domain.com (with my date filled in)
This is what I am getting: "SMTP server problem Invalid SMTP status code in server response"

This is my esmtprc file:
hostname = "smtp.chello.pl:25"
username = "j.s******"
password = "******"

if I remove 25 port esmtprc stuck doing nothing.

Finally I make it work.

I needed an option "helo" in esmtprc.

Finally I managed to make it work as well. It is possible to send contests of file with sendmail but for some reason file I placed at cron (sth.log) was disabled. I could open it do not know why even the script did everything correct and put some data in this file. I had to change a name of this file to this one (sth.*) without log at the end.
The most important thing is working script but if anyone knows the reason I could not open file let me know, please.
