- Mozilla Thunderbird is the University supported
e-mail program. This can be configured to access e-mail via POP
(Post Office Protocol)
or IMAP
(Internet Message Access Protocol).
The
choice between these two
protocols depends on the user’s preferences to
access e-mail on the server.
POP
- Choosing POP means that Thunderbird will be configured to download
all messages from the mail server to the user’s system,
removing it from the server and making it available ONLY on the
computer the user is working on. This means that such messages can no
longer be accessed from other computers through the IT Services Webmail
facility or otherwise.
It
is possible for users to set POP in
Thunderbird and apply a setting to leave the e-mail messages on the
server but if there is a requirement to do so, then such users should
consider IMAP.
IMAP
- Choosing IMAP means that ALL ACTIVE (both read & unread)
e-mail
will remain available on the mail server and will therefore be
accessible from different computers and locations. This is particularly
useful for users who need access to all their e-mail from different
locations e.g. when on campus, at home, abroad etc.
IMAP
users should
monitor that messages do not use all the mailbox storage space on the
mail server. Information about e-mail quota limits and
instructions
to remove messages from the server are available here.
Users
can check whether they are using POP or IMAP as follows:
- In Mozilla
Thunderbird, click 'Tools' menu.
- Choose 'Account settings...'
- Choose 'Server Settings' below Account (left pane
of the Account Settings dialog box). On the right pane, the Server
Type: will display either 'POP Mail Server' or 'IMAP Mail Server'.
- Click OK button to close the Account Settings
dialog box.
Use of
IMAP on IT Services workstations is currently not supported.
Students & staff are encouraged
to use the IT Services
Webmail facility when accessing their mailbox on IT Services workstations.
If
you have Thunderbird already configured on your computer and you would
like to switch from using POP to IMAP:
Follow instruction guide
B*.
If
you are setting up Thunderbird (to use POP or IMAP) on an office/home
computer for the first time:
Follow instruction
guide A*.
*The
guides can be displayed and printed using Adobe Acrobat Reader
available from the IT Services Downloads page.
