• Cloud sharing: Share the desired file via your cloud.
• FileTransfer: Send a file up to 3 GB in size via FileTransfer.

You cannot send files executable under Windows. Sending the following extensions will be prevented for security reasons. This will generate an SMTP error message.

Unallowed extensions:

• exe
• vbs
• pif
• scr
• bat

• cpl
• dll
• doc
• or the corresponding MIME types

Messages coming to you are checked for spam or malware by appropriate anti-spam appliances. Dangerous messages or messages clearly identified as spam are deleted or quarantined. You will be informed about quarantined emails on a daily basis, if necessary.

Alternatively, you can use the Anti-Spam-Appliance to find out about quarantined (Mail quarantine menu item) or rejected emails (Mail log menu item), to release emails from quarantine, and to maintain a personal white and black list.
