Hello,

I got the following error message is my logs: What does it mean?
I don't think I have update this file.

this is the database postfix uses to deliver the mails.

/etc/mail/aliases is the plain text file you can update.
If you didn't update it, check it for any strange user names.
Perhaps you upgraded postfix, could have changed the date stamp of the file?

/etc/mail/aliases.db is the hashed file used postfix.

Run newaliases to update aliases.db
