A follow on to my own post. In my hurry to go have lunch, I failed to note
that simply advertising ETRN isn't enough. qmail-smtpd.c must also
acknowledge an ETRN request with at least a "250 ok". So I added a bit more
code to do that. I apologise to everyone for my mistake.
I added an smtp_etrn subroutine after the smtp_help subroutine:
..
..
void smtp_help()
{
out("214 qmail home page: http://pobox.com/~djb/qmail.html\r\n");
}
void smtp_etrn()
{
out("250 ok\r\n");
}
void smtp_quit()
{
smtp_greet("221 "); out("\r\n"); flush(); _exit(0);
}
..
..
And then the following line in the SMTP commands structure:
struct commands smtpcommands[] = {
{ "rcpt", smtp_rcpt, 0 }
, { "mail", smtp_mail, 0 }
, { "data", smtp_data, flush }
, { "quit", smtp_quit, flush }
, { "helo", smtp_helo, flush }
, { "ehlo", smtp_ehlo, flush }
, { "rset", smtp_rset, 0 }
, { "help", smtp_help, flush }
, { "noop", err_noop, flush }
, { "vrfy", err_vrfy, flush }
, { "etrn", smtp_etrn, flush } <----- inserted line
, { 0, err_unimpl, flush }
} ;
I think this is better. Although the "250 ok" in response to ETRN is not
really needed (I could care less what the client machine thinks of the
response), it is the right thing to do.
