Disable local email delivery on hosted domains
by z3n on Sep.04, 2010, under Linux Happyness
Problem:
There’s some domains on a server that users a external server to process the emails (eg. google servers, aspmx.l.google.com) those emails are all fine when sent from outside the box but when sent from the box they fail to reach the destination or get delivered to a local user.
Solution:
define(`MAIL_HUB', `example.com.')dnl define(`LOCAL_RELAY', `example.com.')dnl
For sendmail, this will make the domain’s emails to be delivered to the ip address assigned at the domain’s MX record.
Note:
This seemed promising for me at first look, but it will redirect ALL local domains to this MX record, ruining everything. Nothing new when dealing with sendmail, anyway when i find a better solution for this i will update this post again.

Itaú shopline class
by z3n on Sep.03, 2010, under Coding
Problema:
A integração PHP proposta pelo Itaú é desastrosa, uma classe compilada em Java que requer um módulo beta descontinuado em PHP.
Solução:
Utilizando engenharia reversa descompilei a classe:

Nada satisfatório, mas é melhor do que utilizar o módulo java beta ou a integração windows emulada no linux.
Também achei um port em PHP, não é uma maravilha, mas dá pro gasto por enquanto.
