smtp service check broken ?

[medic]

i cant explain, but this is odd.

echo 'net.tcp.service[smtp,193.239.17.72]' | nc 127.0.0.1 10050
0

[zabbix@toolbox ~]$ nc 193.239.17.72 25
220 www-17-71.aps-web.de ESMTP Postfix (2.2.4) - APS web.services

doing the same with http works, but also known mailservers like gmx return 0

in svn.zabbix.com/trunk/src/libs/zbxsysinfo/common/common.c

1665 buf[sizeof(buf)-1] = '\0';
1666
1667 if( strcmp(buf, expect) == 0 )
1668 {
1669 *value_int = 1;
1670 }
1671 else
1672 {
1673 *value_int = 0;
1674 }


but:
strcmp(buf,expect) returns 1 on TRUE,
so it's just the other way around ...

FIXED: close.
