Downloading oversized email attachments

When an email message exceeds the maximum allowed size, it’s usually blocked by default. The message size limit settings can be found in the following three places:

  • Content profiles: Under Scan Options when configuring a profile under Profile > Content > Content, you can specify both the message size limits and the actions to take.
  • Domain settings: Under Advanced Settings > Other when configuring a profile under Domain & User > Domain > Domain, you can also specify the size limit at the domain level. The default size limit is 204800 KB. Messages over this size will be blocked, however this should be a large enough limit for most oversized messages.
  • Session profiles: Under SMTP Limits when configuring a profile under Profile > Session > Session, you can specify the message size limits used this session profile. The default size limit is 10240 KB. Messages over this size will be blocked.

However, in some cases, you may not want to block the files. For instance, you may want employees in your organization to send larger files to each other.

In this case, you can use the content profile to catch the email, quarantine the email, and then notify the recipient to download the email attachments from their personal quarantines.

The following example shows how to send and download oversized email messages.
