Fast mailing: optimized multi-threaded mail sending supports hundreds of simultaneous mail send sessions with very low RAM usage.
Automatic error processing: email addresses will be automatically processed and bad addresses are flagged in the database. You can audit the corrected email address list as well.
Highly configurable: you can define exactly who the "From:", "Reply-To:" and SMTP "From " are for every message.
Auditing: every mail transaction is fully logged. You can obtain positive confirmation of mail delivery (or failure) as well as the time delivered, number of retries, or error message obtained for a given email address.
Database links: easily import databases of email addresses and export Lyris information to your database.
Headers and footers: you can specify a header or footer to be wrapped around every outgoing message.
Subscriptions: membership can automatically "expire" after a specified period of time.
Complete security: Lyris can be configured to automatically refuse any connections from the outside, so that only you can use Lyris.
Insider Posting: can assign a number of people to have permission to post to a group.
