Can I use sendmail just for sending email outbounds with dynamic IP address?
Many ISPs have taken to blocking port 25 connections from dynamic IP addesses as these are frequently spam bots. Instead, tell sendmail to use your ISP's smtp service as a "smart host" -- define(`SMART_HOST',`smtp.your.provider') in sendmail.mc, generate a new sendmail.cf by running "make -C /etc/mail" and restart sendmail. Your outbound email will be routed through your ISP's smtp service for delivery.
