Ola Victorio, como comentei no 1o post esse servidor foi legado, ate
entao nao tinha mexido nele. o nilton OS mandou antes uns links sobre
o dovecot....Ontem de noite ja tive uma tentativa frustada de fazer
funcionar. Vou tentar hoje com mais calma e ver se consigo fazer
funcionar com o dovecot.
Nao sou muito manso com postfix, e a pessoa que configurou nao deixou
nada documentado, pelo que pude ver ele foi pegando tutorial daqui e
dali e tentando ate fazer funcionar.
