Bruin OnLine Email Servers

Bruin OnLine provides users with the option of checking your mail using POP or IMAP. Depending on your needs, you can choose to use POP or IMAP.

POP stands for Post Office Protocol and is a simple set of instructions that let your computer retrieve messages from the BOL mail server. Like most POP servers, the BOL mail server uses port 110 for getting mail. After authenticating the request with the user's password, the POP protocol asks the server if there is any new mail, and if your mailbox on the server has messages, then POP usually downloads them to your computer and deletes them off the server.

IMAP stands for Internet Mail Access Protocol and allows a "client" email program to access a message stored at a remote location as if they were on the local computer. Email stored on an IMAP server can be manipulated from a desktop computer at home, a workstation at the office, or a notebook computer while traveling, without the need to transfer messages or files back and forth between these computers.

In order to send email, Bruin Online uses the SMTP or Simple Mail Transfer Protocol using port 25. The SMTP protocol sends your email and any attachments to the the email address specified in the message. If you send a message to an invalid email address, then it will be sent back to you with an error message in the body of the text. Here are the specifications for BOL's mail server:

  • Incoming Mail Server: (POP) mail.ucla.edu port:110 or (IMAP) mail.ucla.edu
  • Outgoing Mail Server: (SMTP) mail.ucla.edu port:25

Using An Outside Internet Service Provider(ISP)

This applies to BOL users who do not use the BOL modem pools or on campus LAN connections to access the internet (includes users with DSL and Cable modem connections). Most ISPs restrict their users to using their SMTP server for security and anti-spam reasons. Your BOL email may be sent using any SMTP server (depending on your ISP) and will still show up as UCLA email. If you use an outside ISP and only have problems with sending BOL email, then you may have to use that ISP's SMTP server to send your mail. Contact their support center in order to find out their SMTP information.
