Hey guys, I was attempting to write a plugin for my qmail-spp enabled |
| 2 |
netqmail package when I ran into the following issue... |
| 3 |
|
| 4 |
hackdmz control # nc localhost 25 |
| 5 |
220 hackdmz.net ESMTP |
| 6 |
ehlo test |
| 7 |
250-hackdmz.net |
| 8 |
250-STARTTLS |
| 9 |
250-PIPELINING |
| 10 |
250-8BITMIME |
| 11 |
250-SIZE 0 |
| 12 |
250 AUTH LOGIN PLAIN |
| 13 |
mail from test@×××××××.net |
| 14 |
250 ok |
| 15 |
rcpt to test@×××××××.net |
| 16 |
451 qmail-spp failure: plugins/validuser.pl: can't execute (#4.3.0) |
| 17 |
|
| 18 |
This shows up in dmesg |
| 19 |

I tried a few different pax flag settings for |
| 32 |
/var/qmail/bin/qmail-smtpd to no avail so for now this binary is set |
| 33 |
to default, which seem too lax to me. What do you guys think? |
| 34 |
|
| 35 |
hackdmz control # cd /var/qmail/bin/ |
| 36 |
hackdmz bin # paxctl -v qmail-smtpd |
| 37 |
