i have postfix set up as a satellite to listen on port 587 i can send email outside fine trough the postfix(ubuntu) box from the local network with no problems
when i try to connect to the postfix(ubuntu) box from a external ip and send mail it spits back a 554 5.7.1 Relay access denied error
i can telnet to it fine, just cant send mail
this is my main.cf :
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no append_dot_mydomain = no readme_directory = no smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_use_tls = no myhostname = cotiso-desktop alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mydomainname.com, cotiso-desktop, localhost.localdomain, localhost relayhost = smtp.mydomainname.com mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all
there is no security set up yet, i'm just trying to get it working first
thanks in advance
thanks pQd i tried with a fixed external ip and it works, but i would like to let more people use it regardless of whether they're connected from, do i have to install something else in order to get it to work?
