This is getting to be a headslapper. Every time I upgrade Ubuntu to a new version, whatever MTA they have decided needs to be there steps all over my built-from-source-just-the-way-I-like-it sendmail package. I suppose I should just figure out how to embrace whatever they've chosen, and configure it to work with my domains and users and what not.
Until I do this, though, no e-mail through the virtual domains! Might be going to Google for e-mail.
i created a lightweight debian package of sendmail. Its a migration of sendmail 8.13.1vas it ran on mandrake linux 10.1. People who like sendmail or even are sendmail adepts want some easy going version of sendmail on their ubuntu desktops with which all the tricks out of the bag with other parties SMTP software and addons work by definition as it was designed. Download is at :
ftp://ftp.crashrecovery.org/pub/linux/sendmail/ubuntu/11.10/ and
