[Mail] Update Postfix changelog

pica-mail/pica-mail-mta/CHANGELOG.md

+# v1.0.3
+
+- Re-open port 25 for incoming mails
+- Move away ENV from Dockerfile (better to have only one self-documented place, ie Compose)
+- Remove `smtps` service from `master.cf` as it is obsolete and not mapped to any host port
+- Remove `virtual_minimum_uid` already set to the default and does not seem useful without `virtual_uid_maps`
+- Remove unused files (old private key, old rsyslog config)
+- Try to clarify some comments (not sure they are tho)
+- Fix syntax for milter filters (from Romain's hotfix on monitoring)
 # v1.0.2
 
 Support for LDAPS
