Trusted Solaris Administrator's Procedures

To Troubleshoot Mail Delivery Difficulties

  1. Check that there is a properly configured network connection between the sending and receiving hosts, as detailed in "To Check Network Connections for Sending Mail".

  2. Check the nsswitch.conf file and the mail aliases repositories.

    sendmail consults the local /aliases file, the NIS map mail.aliases, or the NIS+ mail_aliases table when determining where to deliver mail. Which alias file it consults depends on the nsswitch.conf(4) entry for aliases.

    For example, mail to janez from a process on her Trusted Solaris desktop tern would not go to janez@tern if sendmail consults the NIS+ mail_aliases table and finds an alias of janez@egret in that table for user janez.
