You'll get a warning message $ grep testme /etc/aliases testme: user1 testme: user2 $ newaliases /etc/aliases: line 105: testme... Warning: duplicate alias name testme /etc/aliases: 80 aliases, longest 10 bytes, 812 bytes total I think the second entry will get the mail; aliases are stored as db or dbm files, and so only have one value per key. Sendmail doesn't merge keys. (At least looking at the resulting DB file I only see "user2" in the file). > I know, that "bon.aqua: coke, pepsi" will forward the mails to coke and > pepsi, That is the correct format.
