Calmail bmail uc

It seems like you're trying to communicate something using a combination of letters. Here's my attempt to decipher what you're trying to say:

• Calmail: Could you mean "calendar mail" or "calendar email"?
• Bmail: Is this short for "business mail" or "bulk mail"?
• UC: Could this stand for "University of California" or "University College"?

If I'm correct, you might be trying to ask about a specific topic related to email or communication. If I'm not correct, please feel free to provide more context or clarify what you're trying to say!
