Hi.
I undestood this problem that It was happening,
I was writting the mime wrong in the attachments. I read a file with size
4M and I've converted to Base64, so I've written in the mime the content.
But i wasn't put the lines with 76 ccharacters plus ""/r/n". I was writing
the every in the only line. I think this did the Email Parser uses 100% of
the CPU and It delay mora time.
I packed up and I was sending email very fast.

Thanks
