Troubleshooting your Email


Are you receiving any email at all, from any source?

If you are getting email from people besides the DNA Sequencing Core, your basic email system is working. Go on to the next section.

Your ability to receive email may depend on three separate components: (click on any of the following for definitions)

  the University's X.500 system
  your email server
  your email client

If you have not received email from someone (anyone) within the last day or so, you may want to have your departmental computer experts check on these components for you. You may be able to check a few things yourself:


Does the Sequencing Core have your correct email address?

Sequencing results are sent to the email address of the person who submitted the samples, not the lab's PI. Check the email address entered under your name. Make sure it's correct.

We highly recommend that you give us your email address as 'uniquename@umich.edu', and NOT your full email address (see below for term definitions).

If you ever change your email address, you will probably forget to change your entry in the SeqCore's computer. However, it's more likely you'll remember to change your X.500 entry.

Everything looks OK up to this point? Call the Core's director (Dr. Robert Lyons, 764-8531) and let him know about the problem.


Explanations and definitions:

Email server

Your incoming email is saved on a computer known as your email server. This is usually *not* your desktop system, but instead is usually operated by your department or perhaps by U of M itself (eg. the "IMAP" email servers). Your server is always turned on and always connected to the network, unlike your desktop system. When you you want to read your incoming email, you start up client software on your desktop computer:

Email client

To read your email, you start up an 'email client' on your desktop system. There are far too many client programs to ennumerate here, but they usually do the following:

Your full email address

Your "real" email address is name@something.long.ending.in.umich.edu where 'name' is probably your uniquename (assigned by the University) and the something.long... is the full address of your email server. Most people have trouble remembering such long email names, so the University instituted the X.500 system ...

X.500 system

Since people will usually forget your "real" email address, the University provides a very useful service called X.500, where they take responsibility for remembering your full email address, and anyone sending you email merely has to send it to umich.edu (for example name@umich.edu). A central computer receives your email, looks up your real email address and sends the message to your email server. A few key points:
