Our domain is henryind.com and we use Webmin as IMAP/pop client for the "scan-to-email" function of our printers (hyenryind-printers). Last week this function went down on all our printers. All other printer functions work as they should. All are networked and can be accessed. All printers have the correct settings and port assignment and have been working flawlessly a long time. Last Tues. they ceased to "scan-to-email." What's changed?
