Autoresponding works only for local email addresses (sendmail and vacatoin)
Posted on 2004-04-04
I have sendmail running on Red Hat, and have set up the program vacation to enable autoresponding to users. For some reason, vacation autoresponds only to local users. For instance, when vacation is set up for firstname.lastname@example.org, if email@example.com sends a message to user1, then user2 does get the configured autoresponse message. If firstname.lastname@example.org sends a message to email@example.com, he does not get an autoresponse.
Please note that the mailserver is sitting behind a firewall. The IP of domain.net is obviously that of the firewall which forwards connections to mail ports to the mail server.
Thank you for the help.
