qmail-smtpd.c

[Renato Dobelin]

Ol� for all, I looked for of some forms to prevent leaving the qmail with the opened Relay, used patch of the Mrs. Brisby's to legalize the together smtp with the RPM of the qmail of Bruce Guenter (obviously I created a new package RPM), but exactly thus the qmail still was disapproved in the test with the " telnet relay-test.mail-abuse.org ", the Wildmat I I did not obtain to make to function in my system, I decided to look at qmail-smtpd.c inside and to look a reply of as to prevent the not authorized Relay and found the function "smtp_rcpt(arg)" and includes the following strings:   void smtp_rcpt(arg) char *arg; {   int x=0; /* new code   for(x=0; arg[x]!=0; x++) if ((arg[x]==37) || (arg[x]==34) || (arg[x]==91) || (arg[x]==33)) { err_syntax(); return; } */new code   if (!seenmail) { err_wantmail(); return; }   if (!addrparse(arg)) { err_syntax(); return; }   if (flagbarf) { err_bmf(); return; }   if (relayclient) {     --addr.len;     if (!stralloc_cats(&addr,relayclient)) die_nomem();     if (!stralloc_0(&addr)) die_nomem();   } ...   After to compile the qmail and to restart the job again, I run the " telnet again relay-test.mail-abuse.org " and now it passed in all the tests. The code looks for the characters ",[,!,% in rcpt. I am not programmer and therefore I was with the following one doubts: It will be that I will have problems with emails we legitimos with this alteration?   Renato Dobelin
