I assumed because of the old version of your existing installation a less actively maintained situation and made a snap judgement about your experience. I also never said sendmail is not a solid MTA. I stated it is extremely difficult to maintain. Also other MTA are well suited for high traffic servers.

I do not know anything about your old installation so you have to figure out, how and where the unix socket of the daemon is located. If you use a chroot environment you must make sure the socket is accessible to sendmail. Cheers, -H [...] -- Henning Follmann | hfollm...@itcfollmann.com
