Last time I looked at deliver it seemed like there were very few
conditions it considered as a temporary failure and thus for it to return
EX_TEMPFAIL. I also was considering over-quota conditions (also
filesystem quotas).
The '-e' option to deliver will, possibly by accidental side-effect, avoid
calling the deliver-generated bounce code. Instead deliver will write
some error text on stderr and exit EX_NOPERM.
The code in question is src/deliver/deliver.c lines 810 -- 835 which
occurs right after attempting to save the message (i.e. ret is the return
code from the save attempt). The '-e' option is what sets
stderr_rejection.
if (ret < 0) {
const char *error, *msgid;
bool syntax, temporary_error;
int ret;
error = mail_storage_get_last_error(storage, &syntax,
&temporary_error);
if (temporary_error)
return EX_TEMPFAIL;
msgid = mail_get_first_header(mail, "Message-ID");
i_info("msgid=%s: Rejected: %s",
msgid == NULL ? "" : str_sanitize(msgid, 80),
str_sanitize(error, 512));
/* we'll have to reply with permanent failure */
if (stderr_rejection) {
fprintf(stderr, "%s\n", error);
return EX_NOPERM;
}
ret = mail_send_rejection(mail, destination, error);
if (ret != 0)
return ret < 0 ? EX_TEMPFAIL : ret;
/* ok, rejection sent */
}
As Timo has said elsewhere "deliver could use a rewrite some day..".
