I'm told there are also limits to the number of emails we can send to someone per hour, and a bunch of other flavours of anti-spam. I am seeing mail returns that say: " message still undelivered after 4 hours Will keep trying until message is 2 days old" And " permanent fatal errors " ... " <<< 550-"JunkMail rejected " ... " <<< 550 unattended mailbox " > And if you are looking for a SMTP/IMAP/POP3 server only (I mean no extra > modules like webmail client interface, stats analysis module...)

I'd prefer a Delphi implementation. Although best solution is a better email server.
