[Zope] sending mail from python script, strangeness with symbol ':' in body

[Ruslan Spivak]

Hello!

When i try to send mail from python script and body of message contains 
symbol ':' then i get letter without subject and body.
In MailHost source i found send_simple, when using it i have no 
problems, but with 'send' method i have abovemetioned problem.

I tested with zope2.6.1 and 2.6.2
Your help is very appreciated.

Best regards,
Ruslan
