Qmail and NAT
The problem is: I've a public Ip address that is the MX record of my domain. the port 25 of this public ip is natted to the port 25 of a private address (192.168.5.2), on this server I've qmail of course. After that I've a Microsoft Exchange Server (192.168.5.4) that holds all the mail. I want to make my qmail like a "mail router" now the configuration of my qmail i quite correct, tha mail outbound is delivered, the problem is in inbound mail. I've wrote .mydomain.dm:192.168.5.4 in smtproutes I note that when a mail from external networks to mydomain.dm reaches my qmail, it not send the mail to the exchange server, but try to send the mail to the MX record (the public address) tha isn't reachable from internal network for nat reasons. how i can solve this problem? is a nat or qmail problem?

Solaris vs. Linux vs. FreeBSD
What's is the best OS for run Qmail (and/or Ezmlm)? What advantage and disadvantage has each one? I'll need send two millions mails per day and I don't know what hard can I buy? :) Thanks very much!
smtp router
I need to make this possible with qmail: I've this structure INTERNETQMAIL-EXCHANGE i need that ALL incoming mail from internet are sent directly to exchange and the outgoing mail are sent normally. it is possible? how?
need to log in a database.
I now it is not too legal and a right thing, but I must register in a Database, possibly MySQL or PostgreSQL, every single incoming/outgoing mail with: + sender + receiver + body of the mail + possibly also any attachment how it is possible? thx.

stralloc problem
Hi all, if in qmail-pop3d i declared a variable: stralloc *arrayname; int numm = 30; arrayname = (stralloc *) alloc(numm * sizeof(stralloc)) for (i=0; i

I meant to say, > should the sizeof(stralloc) be sizeof(yourstructure). I hope that > was clear. stralloc is a structure with a int and a char* now i tried to do this declaration: struct stralloc *arrayname; struct arrayname = (struct stralloc *) alloc(numm *sizeof(struct stralloc)) but it doesn't work. Thanks anyway.
qmail-pop3d stralloc problem
Hi all, i have a big program with stralloc variable. So, in qmail-pop3d i declared a variable: stralloc *arrayname; arrayname = (stralloc *) alloc(numm * sizeof(stralloc)) with numm as number of message. When i try to do a stralloc_copys(&arrayname[i], "hello"), qmail-pop3d exit with a "segmentation fault". The strange thing is that i get this error only when numm is great than 25.I thought ...may be a memory problemor most probably i'm not a really good c programmer. Thanks for all your suggest Federico.
