First, your asking how to change the hostname announcement sendmail uses, so I would think you have not added the appropriate entries to sendmail.mc to change your hostname announcement in the first place. So sendmail is using the hostname (canonical name) it derived at startup (I think it issues a gethostbyname). To me, this points to your servers hostname/domain name, resolver lib config problem. At least something along those lines. To answer your question, add the following line to your sendmail.mc file to change sendmails hostname announcement (HELO). Make sure you re-create sendmail.cf define(`confDOMAIN_NAME', `mail.frazerbilt.com')dnl NOTE: I use the above at my end because my mail server sits behind a firewall and its internal hostname is different than mail.mydomain.com (my MX record). So I add this line to make other MTA's happy when they do a reverse lookup based on the HELO my end sends for outbound mail.
