General IMAP Email Configuration Information

Although we have specific instructions for configuring recommended email applications for use here at UVM, you may choose to use an email client that better suits your specific needs.

Note: IMAP-only email clients cannot directly support Exchange calendar invitations, so they will receive a link to the calendar item in Outlook on the Web (OWA).

We hope the following information allows you to correctly configure and use the software of your choice.

Setting: You should enter:
Full name: Your full name
Email address:
Outgoing mail (SMTP) server:
Outgoing mail (SMTP) port: 587
Outgoing mail (SMTP) security: TLS (or, STARTTLS)
Incoming mail (IMAP) server:
Incoming mail (IMAP) port: 143
Incoming mail (imap) security: TLS (or, STARTTLS)
Directory (LDAP) server:
LDAP search base: dc=uvm,dc=edu

Concerning IMAP:

Our IMAP server requires a Transport Layer Security (TLS) secured connection.

In order to keep your Sent mail, Drafts, and Trash folders consistent between OWA and other IMAP clients, be sure that your mail Drafts are saved to the IMAP folder "Drafts", your Trash to "Deleted Items", and your folder for sent (outgoing) mail to "Sent Items".

Concerning Off-Campus Access:

If you wish to use the University's outgoing mail server ( with IMAP clients off-campus, you will need to configure your mail program to authenticate (log in) to the outgoing mail server. The wording of these options varies between clients (e.g. in Thunderbird, "Authentication method: Normal password" must be used).

Also, you will need to specify that you wish your outgoing mail to use Transport Layer Security (TLS). This option may appear as "Use secure connection: TLS" (Thunderbird), or "Server requires a secure connection (SSL)" (Windows Mail).  Note that some products use "SSL" and "TLS" as interchangeable terms (whereas TLS is actually a more current protocol than SSL).  Consult the documentation on each product for further details.

Finally, you will want to configure your program to use the alternative SMTP port 587. Use of this alternate SMTP port will allow you to bypass the blocks on port 25 that many Internet Service Providers have in place.
