• rework pkg-install and pkg-message [1]

• install postfix specific mailer.conf.postfix into DATADIR [2]

• make EAI the default, postfix will reject messages if build w.o. EAI and compatibility_level is set to a value >=1 [3]

• use new notation instead PATCH_DIST_STRIP

• bump PORTREVISION

1. detect if the port is installed without TERM, in this case do not ask the to make postfix the default mailer and respect the env POSTFIX_DEFAULT_MTA. This helps tools like salt, ansible, cfengine and puppet during the first package installation.

2. $DATADIR/mailer.conf.postfix can be used by the tools in 1)

3. Issue noted by Melissa Pilgrim by PM Short description of the issue: If compatibility_level is set to a value >= 1, then postfix set smtputf8_enable=yes. For more information see $ postconf -d | grep compatibility_level and http://www.postfix.org/SMTPUTF8_README.html
