For a couple of days I am trying to configure Postfix/Dovecot, I did my best to follow the guides, I can receive mail but cannot send mail from other mail clients than localhost.
Here is a syslog line regarding to a try from a mail-client from the LAN:
Mar 28 12:37:38 mail postfix/smtpd[12524]: NOQUEUE: reject: RCPT from ***.ru[***.***.64.243]: 454 4.7.1 <***@gmail.com>: Relay access denied; from=<***@mymail.server> to=<***@gmail.com> proto=ESMTP helo=<[***.16.98.44]>
Sending mail from the localhost via mail command:
mail ***@gmail.com
This works as expected.
I don't know where to go further, any suggestions/help would be very appreciated.
My main.cf file looks like:
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings

smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
