Tips on email attachments
Most folk send attachments with their emails; it is a quick, easy way to share a file with the email recipient. However, attachments can have a negative impact on your computer-network infrastructure:
- Emails saved with attachments consume storage.
- Large attachments slow performance and may be rejected by the provider.
- Attachments copied to a distribution list (a group of email users) are copied multiple times, once for each user, which can impact network bandwidth.
In addition, emails received with attachments should be treated cautiously, since attachments may become sources of infection. Basic suggestions when receiving:
- Do not open if the sender is unknown or suspect.
- Limit total attachments to under one Gb; zip files greater than one Gb.
