Bump Quota temporarily increases your quota for a period of four hours. Ten minutes after you perform Bump Quota you should be able to see your inbox/delete messages.

How do I adjust the spam tagging settings on my account?

In order to help combat the spread of spam, LTS has enabled spam tagging using SpamAssassin. By default, SpamAssassin uses a preconfigured set of rules to determine if your incoming mail contains spam. These preferences can be overridden to suit your own individual email filtering requirements. To make adjustments to the default spam-tagging rules, log into Mail Maintenance and click SPAM detection. Here, you can increase or decrease spam detection sensitivity, whitelist or blacklist certain email addresses or domains, or send tagged spam to folders outside your Inbox.

How do I create mail filters?

Mail filters help to manage mail by automatically sending a message to a specific mail folder based on characteristics of the message (e.g., subject line contents, sender, etc). When you create a message filter, it will move any message that meets the filter criteria to the folder you designate. When an email message meets the criteria, it bypasses the Inbox and is moved directly to that folder. These instructions show you how to create a commonly used spam filter in Thunderbird::

How do I send a mass email in Thunderbird using data from a spreadsheet?

If you have a spreadsheet that contains a column of email addresses, Thunderbird lets you email that group of people simply by pasting the column of addresses into the "To:" field in a Composition window. You do not need to make an email list first if you don't need one. However, if the data you want to paste is a list of only 4- or 6-digit Lehigh IDs, you must first append "" to all the IDs. All mass email messages must be sent to full email addresses. Failure to do so can result in the wrong person or people receiving your email! This is because when Thunderbird searches 4-digit IDs against the Lehigh directory, it automatically selects a 6-digit ID if it finds one that starts with the same 4-digits. For example, you may intend to email user "aaa4." But if there is a user with the ID "aaa405" that person would receive the email message instead. Follow these instructions for making full addresses from Lehigh User IDs, then return to this page to continue with the process of emailing the list. When you have email data in a spreadsheet in the form of full email addresses, use these instructions for sending a mass email to the whole list:
