I've got this bit of code:

$entity = MIME::Entity->build
(
Type => 'multipart/mixed',
From => 'blah@blah',
To => 'bloo@bloo',
Subject => "$subject",
)
or die "Error creating MIME entity: $!\n";

$entity->attach(
Type => 'text',
Encoding => 'base64',
Data=>@msg_body
);

$entity->smtpsend;

What happens is, the first line of @msg_body is sent as the email body, but nothing else. If I use:

Data=>join("",@msg_body)

then it all goes in there, but there seems to be no control of line returns. how can I separate each line of @msg_body with a line return?

Thanks.
