Sendmail is a swiss cheese when it comes to security and it is horrible to configure and maintain. Try Postfix, it's my personal favorite ;) Also, you can use amavisd-new for anti-virus, which runs as an SMTP service and it's very easy to implement on postfix. www.ijs.si/software/amavisd Don't leave the unix box defenseless (i.e.: outside the firewall). i'd avise you to either: 1- put it on a DMZ 2- change the rule on your pix so that when inbound SMTP traffic comes to your PIX, it redirects that requisition to the UNIX box. just my two cents. -----Mensagem original----- De: Fush Grubber [mailto:fgrubber@xxxxxxxxxxx] Enviada: qua 1/19/2005 09:31 Para: [ExchangeList] Cc: Assunto: [exchangelist] RE: Relocation of SMTP Service to a UNIX box http://www.MSExchange.org/ Thanks Deshwal, I figured as much that this is what i am required to do, but how do i configure exchange to forward all mails to a smart host? i plan to use sendmail on a unix box, is this advisable? >From: "Deshwal, Chand" <CDD@xxxxxxxxxxxxx> >Reply-To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx> >To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx> >Subject: [exchangelist] RE: Relocation of SMTP Service to a UNIX box >Date: Wed, 19 Jan 2005 16:22:53 +0530 > >http://www.MSExchange.org/ > > This needs to be done at two ends. > >1.
