Hello I'm trying to make a mail-setup for my home network. I was thinking about using postfix, because many claim it's better, and, more important, more secure than sendmail (I don't know if it's true). But I have some difficulties setting both of them up, posfix is completely dead in the water (was like that out of the box), sendmail can deliver local mail. What I want to do is the following: Clients in the network (Win9x and Linux) <--> firewall with sendmail or postfix running <--> internet static IP eth0, DHCP address from ISP - eth1, static IP I have one mailbox with my provider, it's something like guy123@isp.com, they have a POP3 and SMTP server: mail-in@isp.com and mail-out@isp.com The SMTP server of my ISP filters relaying, and access to other external SMTP's is blocked. Ditto for external connections to all my ports below 1023. What I want to do is the following, we have a number of mail address we use at home (like extra flashmail addresses, etc.) I want to set all clients up to send mail via my SMTP server, which sends it further to my ISP, but preserving the original FROM and REPLY-TO fields of the message. And for a number of addresses, I want to receive them on my server and have them delivered to local spools. I got the sending part working once with these parameters (in sendmail) # "Smart" relay host (may be null) DSsmtp:mail-out.pandora.be # who I masquerade as (null for no masquerading) (see also $=M) DMpandora.be It works, but if I send a mail: FROM guy.van.sanden@isp.com, it arrives as FROM: gvs@isp.com (gvs is my local userid.), and you can't reply to that because the address belongs to someone else. I would also like to send mail like FROM: me@flashmail.com or something... At this moment, all my clients are configured to use mail-out@isp.com to send mail, but the from header can be whatever I fill in. Can this be done? Thanks for any help! Guy
