Just wondering, looking at the source code, it should be possible to create a merge mode for postalias. Would you accept a PR for this? So the use case would be something like
cat /etc/postfix/aliases /etc/postfix/aliases.d/* | postalias -Mi aliases And it would merge together records if there were duplicates.
