Avoid downloading large attachments in Mozilla Thunderbird - Intertuto

Avoid storing large files that people send to you locally in Mozilla Thunderbird, in Thunderbird 0.9, Netscape, and Mozilla.

          For POP accounts, you can completely prevent local copies of large messages from being downloaded, and in an IMAP account, you can prevent Mozilla Thunderbird from keeping them.

The big files people send

You should know that among your many friends some are special and others have special habits. Among these many friends, you can have one or two who send you messages with huge email attachments like whole movies or multiple photos. Having close friends does not mean that you have to love or watch all the videos they shoot. On that, Mozilla Thunderbird, Netscape or Mozilla SeaMonkey can help cousin.

 Click on the Thunderbird menu button (hamburger) in Mozilla Thunderbird;

 Select Preferences / Account Settings from the menu;

 For IMAP accounts:

• Go to the Synchronization and storage category.

• Make sure that the option Do not download messages larger than ___KB is checked.

 For POP accounts:

• Access the Disk Space category for the desired account.

• Make sure that Messages greater than ____KB is checked under To save disk space, do not download.

 Enter the maximum size of messages that you want to be downloaded automatically by Mozilla Thunderbird.

• The default value of 50 KB will allow it to download most messages containing little or no attachments, while avoiding almost all e-mails with attached files.

 Click OK.

As you open the messages, Mozilla Thunderbird will download them but do not keep the copies offline.

Messages larger than the number specified during download or offline are now truncated by Mozilla Thunderbird, Netscape or Mozilla and there you can download the full message there.

Download the full message on demand
