General Email Information
- Incoming Mail Server (POP, IMAP): mail.lmi.net
- POP Port: 995
- IMAP Port: 993
- Outgoing Mail Server (SMTP): mail.lmi.net (Use SSL with port: 465)
We have provided specific instructions for several popular Email clients. See our main Supportpage for a list of them.
In general terms, you will need to set up your software to use mail.lmi.net for incoming and outgoing mail. We support both POP and IMAP mail protocol. SSL Enctrption is supported (and encouraged!)
POP (Post Office Protocol) is the most commonly used method of retrieving email from a mail server. The majority of our customers are using POP to download their email messages to their local mail client software.
POP is a good choice if you primarily use just one computer. Since all your email is kept on your own computer, searching through your mail is much faster. Plus, you can access your email when your computer is off-line. POP users also do not have to worry much about disk quotas on the mail server.
IMAP (Internet Message Access Protocol) is system where your email is stored in a database on the mail server, and your email client software simply views the messages that are on the server. Any mail folders that you create in an IMAP account are actually created on the server, and not on your computer.
IMAP is a great choice if you regularly use more then one computer to check your email, or if you are a regular Webmail user. Since the email is kept on the server, when you connect from any computer you can see all your mail folders and the email stored in them. If you compose and send a message from our webmail interface, that message will also show up in the “Sent” folder in your email client software. On the downside, IMAP users will need to periodically move mail off the server in order to keep under your disk quota. (you can see your current quota usage in our webmail interface, or within most IMAP mail clients)
If you are not getting internet connectivity from LMi, then you must turn on password authentication for the outgoing (SMTP) mail server in your email client software. Use the same login name and password as you do for your incoming email. Alternately, you can use the outgoing SMTP server address that your access provider assigns to you.
Note that many ISPs (not LMi) will block outgoing connections to the standard SMTP port 25. This is done to combat spam. If you find you are unable to connect to our outgoing mail server, you can change the port number to 2525.
If you are using password authentication for outgoing email, we recommend using either SSL or TLS encryption, otherwise your email password will be sent over the net in plain text format. SSL (Secure Sockets Layer) is more common, and is supported by most email client software. If you use SSL, you need to connect to port 465.
TLS (Tranport Layer Security) is a more modern security system, but is not as widely supported in email client software. Mozilla Thunderbird does support TLS. If you use TLS, you need to connect to port 25 or 587
- Our mail servers are running Debian Linux
- The mail MTA (SMTP) is Postfix
- POP and IMAP service is handled by Dovecot
- The Webmail interface is SquirrelMail
We are currently using 2 spam RBLs to control spam
If you find that a particular person is unable to send you email due to be blocked bu one of these RBLs, let us know and we can add that person’s server to an allow list.
Each incoming message is limited to 50MB including attachments, and each outgoing message 50MB including attachments. Bear in mind that when files are attached to email messages, the attached file must be first encoded by your email software, and that process may increase the actual message size.
Certain types of attachments (such as .exe or other executable files) cannot be sent by email except as .zip files.
There is a limit of 70 recipients for any individual message. Messages with more than 70 recipients will not be accepted for relay. If you need to send messages to a larger list of people, you will need to break up your recipient list into smaller chunks. To maintain large lists, use our Mailman list manager.
