Let me address your points as good as I can:

1. No need to change anything. Just append akapost.com to the original mail address. This will send the mail directly to Akapost which will then strip it off the information from the original email and forward it to the recipient.

2. Only 1. You can delete the akapost substitute and create a new one in the interface.

3. A test with an attachment of 2.2 Megabytes was successful. I do not know the limit though.

4. See 2

5. Large companies would not do that and you might have overlooked the fact that Akapost Premium supports custom email addresses that can be used.

1. In looking around the site, I didn’t see anything about how the service works when you append the akapost.com to the end of the real email addr. Do you have to change Outlook (POP3) account settings to go to their email server and not your regular one? I would think so for otherwise I would expect your regular email server to bounce the message since it would not be able to resolve the email address with akapost.com at the end of a normal email address.

2. There is no mention of the number of email addresses you can give yourself at akapost. It seems like it would be only one. Disposable email systems typically allow many “fake” email addresses.

3. There is no mention of attachment sizes supported (if any).

4. What happens if you start getting spam through your akapost address?

Lastly, I don’t see why companies would want to maks employee email addresses. I would be quite suspicious to get a company email with an akapost address.
