Electronic
Mail
on the Unix Cluster
Email
service can be very slow on blue.unix, since it is designated
to be used mainly as a "number-cruncher" by users who run programs
requiring millions and millions of calculation. The Central Mail Service
may be a better option. If you have been registered on unix.mail,
please check one (or both) of the following for instructions on changing
to the CMS:
If you are
logged in on blue.unix most of the time and want to receive your
email on the Cluster, your Unix account will be set up to do this. If
you use Eudora or Netscape to read e-mail, certain configuration options
must be set for these programs to work. Instructions for making these
changes can be found by selecting one of the following links:
When users
receive email on the Cluster, they will see some peculiarities in their
electronic mail, including the following:
- Each
person's return address will change to include the name of the computer
to which their mailbox is moved. This action does not require you to
make any changes.
- Some
of our customers use Eudora or Netscape to read their
mail. They sometimes find it frustrating to try to read their messages
when that machine is slow due to a large computational load. ITC encourages
these people to move their mailbox to the Central Mail Service. They will still be able to
use their preferred mail program (Eudora or Netscape)
but will find access to their mailbox much faster as the Central Mail
Service computer is reserved strictly for electronic mail; computational
jobs are not allowed to be run there.
- If you
are subscribed to one or more electronic mailing lists, ITC will provide
a way for you to send a message to the list management address that
will allow you to unsubscribe as if you were sending the message from
the old system. (See the Cluster Tools document for more details.) When you have
received a message from the list management site that you have been
unsubscribed from the list with your old address, you can then subscribe
to the list with your new address.
- If you
use the Unix system for computational purposes as well as for electronic
mail, you may continue to receive mail on the cluster. Your return address
will change to reflect the name of the cluster, which will be unix.mail.virginia.edu.
Instructions for updating Eudora, Netscape 3.x, and Netscape 4.x (Communicator) configurations are presented
below.
Eudora
NOTE:
You do not have to change any other settings than the ones listed below
to change to the Unix cluster. If you have any other questions about configuring
Eudora, please read the ITCWeb page on Eudora or send e-mail
to consult@virginia.edu.
- Select
the Personal Info category in the Options window. Change
the Return address: value to "your-computing-id@virginia.edu"
if it is not already set.
- Macintosh
users should now click the OK button to finish; Windows users
need to make a couple more changes and should do the next few steps.
- Click
on the Checking Mail option.
- Click
on the button beside "Status: headers." This button appears in about
the middle of the dialog box pictured below. This option prevents Eudora
from downloading your mail again after making the change to blue.
- Click
OK to close the Options window.
Netscape
7.x (Communicator)
ITC does
not recommend using Netscape to read electronic mail; there are better
and more secure programs for reading mail, such as Simeon,
Eudora,or or one of the
Unix mail programs. However, if you use Netscape to read electronic mail,
you will have to change your Netscape configuration if you choose to migrate
to the Central Mail Service.
Note:
These instructions are for those currently using Netscape 7.x to read
their electronic mail messages. The instructions do not provide full
Netscape configuration information.
- Click
Edit from the menu bar at the top of the Netscape mail window.
- Click
Mail and newsgroup account settings from the drop-down Edit
menu.
- Click
on the add account button, and fill in the appropriate information.
- Click
on pop3 when it askes for mail server type.
- In the
Outgoing Mail (SMTP) Server box, enter
smtp.mail.virginia.edu
- In the
Incoming Mail (POP3) Server box, type:
unix.mail.virginia.edu
NOTE:
If you have selected "Leave on server" (under "After delivery:"),
then periodically you must clean up your server mailbox manually. To
do so, telnet to the cluster and use a Unix mail program, such as Pine,
to delete the accumulated messages. If you have chosen "Remove from
server", then your email will be deleted from the Unix mail server
each time Netscape copies new messages to your local computer.
- Your
Mail Server dialog box should now resemble:
- To set
the time interval for Netscape to use for checking for new mail, click
on server settings. Select the "Check for mail every x minutes"
option, and then enter a value in the edit box. ITC recommends setting
this option to 10-15 minutes.
- Click
OK to exit. Netscape Communicator should be ready to use.
Pegasus
Mail
- Start
Pegasus Mail.
- Click
on the File menu.
- Click
on the "Network Configuration..." item.
- You now
see a dialog box similar to the following:
- Click
inside the POP3 Host field and replace the current setting with:
unix.mail.virginia.edu
- Click
inside the SMTP field and enter:
smtp.mail.virginia.edu
- Click
on the OK box to change the settings.
- Pegasus
Mail is now ready for use.
Umenu and
Unix Mailers
If
you use Umenu or one of the Unix mailers (Pine, Elm, Upenelm, Mush) to
read your e-mail, the only thing that you will need to verify is the name
of the machine that you log into. You should to log into blue.unix.virginia.edu
to read your e-mail.
One side
effect of the Cluster's mail configuration is that e-mail which is copied
to your "sent-mail" folder or is received from yourself as part of a mailing
list will have an alternate address in the header. This does not affect
the functionality of your email, but there is a workaround for those who
find it bothersome. Please see the FAQ document
for instructions.
