Increasing size limits in session profiles
As mentioned in the introduction to this recipe, the default size limit for domain settings is approximately 204800 KB (or approximately 200 MB). This is the system maximum limit. However, the default 10240 KB session profile SMTP size limit will not allow oversized messages. This setting can be increased.
- Go to Profile > Session > Session, select the inbound session profile you want and click Edit.
- Expand SMTP Limits and enter 204800 in the Cap message size (KB) at field.
- Click OK.
