Well,
Here the problem happens with any size of e-mail´s.
The exactly error reported is:
Servidor: '127.0.0.1', Protocolo: SMTP, Resposta do servidor: '553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)', Porta: 25, Segura (SSL): Não, Erro do servidor: 553, Nº do erro: 0x800CCC79
Remembering that this is using W98/OE with e-mail shield on. When disabling this shield all e-mail´s are send well.
Any ideias ??
