postfix-server-setup's Issues

DMARC policy tweak?

Hi,

First off, AWESOME work!
I ran into issues sending test emails to my GMail account due to the strict "reject" value of the sp tag in the DMARC record - suggested through the script, also, some checks complained about the lack of rua entry in the record.
You may want to add these as details/comments/hints somewhere.

After these two minor tweaks, this all works like a charm. I can't thank you enough.

Exit IP

What's the intention for the exit if. Is it to gte the value of inet (IP)

extip=$(ifconfig|grep 'Link encap\|inet '|awk '!/Loopback|:127./'|tr -s ' '|grep 'inet'|tr ':' ' '|cut -d" " -f4)

Because the output i got from ubuntu is

netmask
netmask

Package 'postfix-policyd-spf-python' has no installation candidate

apt-get install -qq -y postfix postgrey postfix-policyd-spf-python will fail for postfix & postgrey since postfix-policyd-spf-python does not exist.

This breaks the mail server section, can be fixed by installing postfix manually like so:
apt-get install -qq -y postfix postgrey
but the python spf part is left out, so a longer term solution is needed.

Can't ssh to vps after running script

It seems that the script do something to iptables, and port 22 is no longer available. (vps provided by google cloud)
Here's the log.
