Send large files

Easy, secure and without media disruption

“Attachment size exceeds the allowed maximum” – how much administration effort and headache has this Outlook message already caused you? With NoSpamProxy Large Files you can send large attachments by email without any problems!

The Radicati Group’s regular reports on worldwide email usage show that the average size of files that users want to send by email attachment as large files is increasing dramatically from year to year. As a result, email infrastructures are heavily burdened and the sending of large files is restricted or generally prohibited by setting limits. In individual cases, the limit must then be increased or an FTP upload or download must be approved by an administrator on an individual request. Avoid these problems and rely on NoSpamProxy Large Files.

Keven Kanet, Head of IT Infrastructure, OLYMP Bezner KG

NoSpamProxy Large Files FAQ – Frequently asked questions and answers

With NoSpamProxy Large Files, companies can send large files securely via email without circumventing the size restrictions of traditional mail servers. Instead of sending the file directly as an attachment, it is automatically stored on a secure platform.

The recipient receives a secure download link via email, which can be used to access the file. This reduces the load on the email infrastructure and at the same time enables controlled, traceable file transfer.

This method is particularly suitable for sending sensitive documents, large CAD files, or extensive media content – GDPR-compliant and integrated into the existing email environment.

The maximum file size allowed for NoSpamProxy Large Files depends on the respective configuration.

In NoSpamProxy Server, you can set the maximum file size allowed for your company yourself, thereby adapting secure file transfer to your IT and compliance requirements.

In NoSpamProxy Cloud, the maximum file size is 1 GB. As an administrator, you can reduce this.

Yes, large files are transferred in encrypted form with NoSpamProxy Large Files. Both uploads and downloads are carried out via secure, encrypted connections.

Additional security mechanisms such as password protection or access restrictions can be activated as an option. This ensures that only authorized recipients can access the content provided.

The encrypted transfer of large files plays a key role in protecting sensitive company data, personal information, or confidential project documents from unauthorized access.

Yes, download links can be time-limited. Companies can define how long a shared file is available for download. Once the specified period has expired, access is automatically deactivated.

This feature significantly increases security when sending large files, as sensitive content does not remain permanently available online. Additional restrictions such as a limited number of downloads or password protection can also be set up.

This allows companies to maintain control over their sent files at all times and reduce the risk of unauthorized disclosure.

Unlike public file-sharing services, NoSpamProxy Large Files is specifically designed for secure file transfer in a corporate environment. The solution is integrated directly into the existing email infrastructure and is subject to central security and compliance guidelines.

While public services are often operated outside of corporate IT, NoSpamProxy enables controlled, traceable, and GDPR-compliant data transfer. IT departments retain control over storage location, access rights, and retention periods.

This makes NoSpamProxy Large Files a professional alternative to services such as WeTransfer – with higher security, better integration, and clear governance.
