Hi, I am a newbie when it comes to linux, but trying to create working email server. I have installed ISPConfig , created new inbox, linked to Thunderbird, but when I send an email to my Gmail account, I never receive it (and vice versa - the emails from Gmail never get to my new inbox) I followed this thread: https://www.howtoforge.com/community/threads/ispconfig-3-send-receive-mail-not-working.44611/ And when I run service amavis start I am getting this error message: Starting amavisd: head: error reading ‘/etc/mailname’: Is a directory The value of variable $myhostname is "pluto", but should have been a fully qualified domain name; perhaps uname(3) did not provide such. You must explicitly assign a FQDN of this host to variable $myhostname in /etc/amavis/conf.d/05-node_id, or fix what uname(3) provides as a host's network name! In the /etc/hosts there is "pluto" linked to my IP Also when I run hostname and hostname -f, I am getting pluto. Any help here? Thank you!
