No, if ActiveSync does not allow you to send out email, your only remaining option is IMAP (in) and SMTP (out). Just be sure you enter your account info in the SMTP (Outgoing) settings. Without SMTP authentication, shaw mail servers will reject your outgoing mail.

Another possibility is that your IP address is blacklisted.

Isn't that what I said (twice)? Restarting modem may resolve it if you get a different IP address. We normally get a different IP address on modem restarts but cable modem can sometimes stick to the same IP regardless of the fact that it is dynamic IP. Also, if the entire subnet (or network) is listed as having a poor reputation, which is not unusual, modem restarts and getting different IP address(es) will not resolve the problem. It's still worth a try. Good tip.

You have the returned mail. Check it. Is this your own broadband connection at home/work? If it is, why don't you try Babowa's suggestion first? It's easier.

from the website:

You can find this in the bounce message you received; it is not necessarily the IP of the Internet connection you are currently using.

Follow that instruction: "additional outgoing mail servers can be configured for mail accounts in Settings > Accounts & Password".

Check your Outgoing mail (SMTP) settings. Make sure you type in your username and password there.

This is the correct settings:
