The default attachment size limit is 30 MB. Emails that are larger than 30 MB will be automatically rejected.

However, this limit can be changed. To do so, please login to your SpamExperts Control Panel.

Please refer to this guide here on how to login into your SpamExperts Control Panel

1.    After logging in, go to SpamExperts dashboard panel > Email Restrictions > Email Size Restriction.

2.    You can change the default attachment size limit of 30 MB here (up to 2048 MB) or set to "No Limit".
However, we recommend that attachment sizes do not exceed 100 MB for performance reasons.

3.    You can also change the default action for over-sized messages here. The emails can either be quarantined or rejected (deleted).
