Is my Softalk Mail Server licence valid for one year or is it permanent?
The license you buy is a permanent license.
However, you should note the following. Your purchase of Softalk Mail Server includes 12 month maintenance, which gives free version updates, free email support and a single telephone support incident.. This is renewable, annually. Failure to keep your mail server program up to date could result in loss of service, should there be changes in mail standards, protocols or spam/virus activity.
