How Do I Read Email at SEAS?

At Penn Engineering, users have several email programs to choose from. CETS recommends the following combination: use Thunderbird under IMAP configuration when reading mail from home, work, or your laptop, and use Webmail when reading mail elsewhere. CETS recommends picking one client and sticking with it, as using more than one at a time can result in lost mail. Never use more than one client simultaneously, as inbox corruption and mail loss can result. The rest of this article contains more detailed information about the several email clients SEAS supports.


Email for all incoming students will be available via Google@SEAS by default.

Google@SEAS must be activated by setting an initial password at the Google@SEAS Account Management page:

Existing users who are not reading email at Google@SEAS can do so by clicking on the Turn on Google@SEAS forwarding button.

After setting a Google@SEAS password, log on at:

Text-Based Clients

The clients in this section require you to log into Eniac's Unix shell. For information on logging in, please see How Do I Log Into Eniac?


Mutt is a text-based email client for Unix-like systems and is preconfigured on SEAS servers such as eniac. When logging into your eniac account to read mail and in general, be sure to use SecureCRT or SSH (not telnet) to connect to eniac. Don't forget to log out of your account when you are done.

To start Mutt, type mutt at the Eniac command prompt.

For additional documentation on using Mutt, see:


Pine is not widely used, but provided for those who already know how to use it and is minimally preconfigured on SEAS servers such as eniac. Pine is less customizable than Mutt but is more user-friendly with its menu-driven format and clear instructions at every screen.

To start Pine, type pine at the Eniac command prompt. Note that the program actually installed on SEAS servers is Alpine, the successor to Pine.

For documentation on using Alpine, see:
