I have installed postfix, and when I tried to send a mail to gmail it told me that it has been sent, but when I checked my inbox in Gmail I didn't saw it.
This is how the connection looked like:
$ telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 DarkSenic ESMTP Postfix (Debian/GNU)
HELO localhost.localdomain
250 DarkSenic
MAIL FROM:<test@test.com>
250 2.1.0 Ok
RCPT TO:<mymail@gmail.com>
250 2.1.5 Ok

Subject: Test

.
250 2.0.0 Ok: queued as E15692031E9

221 2.0.0 Bye
Connection closed by foreign host.
And this is my main.cf file:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name. The Debian default

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

myhostname = DarkSenic

mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0

This is what I get in the log file:

Why doesn't it work? and how can I fix it?
I found some answers on the internet but they didn't work for me…
Thank you for reading and have a nice day 🙂

On Debian, postfix doesn't read
/etc/services, but expects these files to exist in thequeue_directory(usually /var/spool/postfix). So it is actually trying to read/var/spool/postfix/etc/services, which either doesn't exist or is corrupted.Try recreating this file, or better yet just link it (if you aren't running postfix in a chroot).
If you are chrooting postfix, copy the file instead.
