Users
The content of outgoing emails should be checked because sending out spam / malware can damage your corporate reputation. Often the outbound email path bypasses the system that scans incoming emails from the internet, and instead sends the emails directly out to the destination. Filtering the outgoing user's mail also prevent spam from reaching end user mailboxes.
Configure User's Email Client for Outgoing Mail Filtering
The email clients of the users added for outgoing email filtering must be configured to point to CASG service.
In the Account Settings interface of the user's email client, enter the following details:
- Smtp server: mxpool1.spamgateway.comodo.com (for EU based service) or mxpool1.us.spamgateway.comodo.com (for US based service) according to your preferred CASG service domain.
- Connection Security: STARTTLS or SSL
- Port : 587
- Username: [[email protected]]
Open the outgoing users interface:
- Click 'Outgoing' > ‘Users’:
The 'Users' interface of the selected domain will be displayed:
- Click anywhere on the 'Filters' strip to open the filters area:
You can filter results by the username:
- Username: Type a user’s email address in the text box (column 3) and select a condition in column 2.
Click anywhere on the 'Filters' tab to close the filters area. Click the 'Refresh' button to remove filters.
You can add multiple filters to the same search

- Enter the username for the new outgoing user that will be first part of the email address. For example, testuser. The email address of the added user will be [email protected].

- Click the 'Edit outgoing settings' button to configure outgoing settings for the user. The 'Add outgoing settings' dialog will expand:
- Automatic lock - CASG will prevent a user from sending mail if it detects they have sent out spam or malware. You can set the length of this ban in the 'User lock timeout' field.
- Maximum unlocks by timeout – The number of times the locked out user will be unlocked for sending out mails. After reaching the maximum limit, the user will be locked out from sending any mails till it is unlocked by the administrator.
- Limit per month – The number of mails that can be sent per month
- Limit per week – The number of mails that can be sent per week
- Limit per day – The number of mails that can be sent per day
- Limit per hour - The number of mails that can be sent per hour.
- Maximum number of recipients per day - Maximum number of recipients that a user can send mails per day.
- Maximum days to retry - Maximum number of days CASG will retry to send queued outgoing mails after which they are bounced to the user.
- Quarantine response – Determines the response that CASG will send to the SMTP server that delivered a message in the event that the mail is identified as spam.
| Note: If you have enabled quarantine functionality, then spam/malicious mail will be quarantined (and not delivered to the recipient) regardless of your choice here. These options merely determine what message CASG will send back to the SMTP mail server. |
Options:
- Rejected - Will inform the SMTP server that the email wasn't delivered to recipient. (By default is ‘Rejected’.)
- Accepted - The senders will not be notified if the outgoing mails are detected as spam. They will be blocked and not delivered to recipients.
