Postfix: can't connect to localhost but can connect to 127.0.0.1?
For some reason I can’t seem to connect to postfix using ‘localhost’. The command 'telnet localhost 25’ returns the following:
Trying 127.0.1.1... telnet: Unable to connect to remote host: Connection refused
My /etc/hosts file looks as follows:
127.0.1.1 localhost localhost.localdomain droplet.ip.address.here example.com ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts
/etc/postfix/main.cf (relevant section):
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = localhost alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = loopback-only inet_protocols = all
Could anybody help me solve what’s going on?
