Extra blank lines in body of email

[glocamp]

Whenever I send an email that has more than 1 paragraph in the email  body, I like to insert a blank line between the paragraphs. If I include a different email address for myself in the BCC field, I will see that there are 2 blank lines between paragraphs. This is also how the email appears in the Sent folder.

How do I correct this? There is no need for 2 blank lines.

When you get to the end of the last sentence in the first paragraph, are you hitting the Return key once or twice?  If you hit it only once it should double space it as is normal for a paragrah with two blank lines.  Using Bcc or Cc wouldn't have any effect on it.

I realize BCC has no effect, that should be obvious. I use BCC so that I can see what the email will look like to my recipients. 

I don't agree that paragraphs are normally separated by two blank lines.  No other email server that I use does this, so it is an abnormality to me. I only wanted a way to correct this to one blank line, but this does not sound possible. This email server is truly a strange bird.
