We handle incoming SMTP connections via inetd-invoked sendmail on our largest mail server (20,000+ accounts) and our two external mail relays. Those are Sun Solaris systems (6-proc. E4000, 1-proc. E250 and 4-proc. E450) and handle tens of thousands of SMTP connections per day. No ill effects ; we are working like this for over a year. The /etc/hosts.allow file now allows us to return a particular SMTP code to a certain host or to divert incoming messages in an alternate queue, which is a great help to put virus-infected PC's "in quarantaine" for a while to verify whether they behave properly following disinfection. Feel free to e-mail me for examples or discussion. Eric Luyten, Computing Centre VUB/ULB.
