Re: Strip "received from" headers from Submitted Mails
[In reply to]

Hello,
I had the same problem. I patched my installation somewhat such that
_if_ the use was able to authenticate himself properly the received-from
would be stripped. This of course relies on a variety of ssl and
smtp-auth patches. So I'm not sure whether I can simply provide you with
a working patch. I can however provide you with the only fuhnction I had
to modify to achieve the required result. The main change was the
addition of the line 'if (!authd)' in the TLS ifdef. of the smtp_data
function in qmail-smtpd.c
void smtp_data() {
int hops;
unsigned long qp;
char *qqx;
#ifdef TLS
stralloc protocolinfo = {0};
#endif
if (!seenmail) { err_wantmail(); return; }
if (!rcptto.len) { err_wantrcpt(); return; }
seenmail = 0;
if (databytes) bytestooverflow = databytes + 1;
if (qmail_open(&qqt) == -1) { err_qqt(); return; }
qp = qmail_qp(&qqt);
out("354 go ahead\r\n");
#ifdef TLS
if(ssl){
if (!stralloc_copys(&protocolinfo,
SSL_CIPHER_get_name(SSL_get_current_cipher(ssl)))) die_nomem();
if (!stralloc_catb(&protocolinfo, " encrypted SMTP", 15)) die_nomem();
if (clientcert.len){
if (!stralloc_catb(&protocolinfo," cert ", 6)) die_nomem();
if (!stralloc_catb(&protocolinfo,clientcert.s, clientcert.len))
die_nomem();
}
if (!stralloc_0(&protocolinfo)) die_nomem();
} else if (!stralloc_copyb(&protocolinfo,"SMTP",5)) die_nomem();
if (!authd)
received(&qqt,protocolinfo.s,local,remoteip,remotehost,remoteinfo,case_diffs(remotehost,helohost.s)
? he
lohost.s : 0);
#else
etcetera...
I hope this helps you forward,
With kind regards,
Werner,-
