an effort to mitigate the risks and proliferation of computer viruses,
worms, and spam, many Internet Service Providers (ISPs) are implementing
various controls over incoming and outgoing email service. Some of
these controls and processes may affect the way members of the FDU
community receive and/or send Email, primarily from off campus locations.
This memo serves to offer three solutions that users can implement
should their ISP block, or begin blocking, outgoing Email.
The methodology implemented by many ISPs, and under consideration
by many others, is to block Port 25 traffic. This implies that outgoing
email traffic will either need to go out through the ISP’s
email server or it will be blocked. Therefore, members of the FDU
community using an email client such as Outlook or Pegasus Mail,
configured to use the FDU mail server for incoming and outgoing
mail, will be unable to send mail using their ISP’s connection.
There are three methodologies that can be implemented to alleviate
the difficulties in accessing email if an ISP has blocked Port 25
Users can access E-mail using the Webmail interface, accessible
from any web browser. Using the Webmail interface provides a direct
connection to the FDU email server and bypasses Port 25 traffic
blocking. The Webmail interface can be accessed from any browser,
is ISP independent, and offers the most ubiquitous service.
Users can implement a Virtual Private Network (VPN) connection between
their computer and the FDU network. This methodology offers secure
remote access to university network resources and the Internet.
However, this does require the installation and configuration of
VPN client software on a user’s computer.
Users can create additional email client configurations that will
access email using different incoming and outgoing email servers,
depending upon user location. For example, Outlook can be configured
to have two or more client configurations. One configuration might
be used when the user is logged onto the FDU network while on campus,
and another might be used when the user is at home using an ISP.
Each configuration will be set up to use the correct incoming and
outgoing email servers.

creating additional email client profiles, can be found at following

Center (UTAC) at extension 8822 for guidance and support. The UTAC

It should be noted that Port 25 blocking is implemented by ISPs
and not FDU. In response, the technical teams at FDU will continue
to monitor industry trending and offer up proactive measures to
minimize disruption to important services.
