Malware can redirect the SMTP/IMAP connection to itself like many antivirus software does. Or maybe it sniffs on the local network, but I don't guess it's very effective in switched networks (hmm or maybe public wifi). Good idea about requiring SSL/TLS. Is there any overview if there are clients/mobile devices actively in use which don't support it? For example will Outlook without SSL/TLS configured use it server will require it? BTW the FTP stealing is still a threat, if I remember it steals passwords from Total Commander. That's why we enable FTP from exotic countries (geoip) only on request. -- bYE, Marki
