Hi all, Koha 16.05.03 on Ubuntu 14.04 LTS (Amazon AWS) We're running Koha on a separate VPS from our organization's network. We are using a our library's generic email address, which is a Microsoft Exchange server organization email address. We are trying to get our Koha VPS to successfully deliver notices to emails within our network domain. We are running Sendmail on our Koha box, and Gmail, Yahoo, and Hotmail accounts (after users whitelist our library email address) emails are being received successfully. Emails are not successfully delivered to our organization's email domain. What we want to do is channel all email notifications coming from our Koha VPS through our Microsoft Exchange server, so that they are seen as coming from our network, do not get flagged as spam, junk, etc., and so that they are successfully delivered to inboxes. Has anyone done this with their Koha set-up? Is this a sendmail config file modification, a sendmail Perl module configuration, or something else? Thanks all! Craig Butosi, MA, MLIS, B Mus (Hons.)
