How do I set-up a mailbox using IMAP on my device?

Our standard and premium mailboxes can be loaded onto your device or through your mail client either with a POP3 connection or an IMAP connection.

By using an IMAP connection, you can have multiple clients simultaneously connected to the same mailbox.  For example, you can have email on your phone, your tablet, and your computer, and when you delete a message from your phone, it will also be deleted on your other devices.

The way your device or mail client is designed may be different than how other programs or devices work, with different names for the same steps.

Your device or program should have detailed information on how to add and set up mailboxes onto the system, but there are general pieces of information you need to complete the process.

When selecting the account type, select IMAP.

Your Username is your full email address.

Your Password is your mailbox password, which you can find in your Control Panel.

Your Incoming Mail Server and Outgoing Mail Server are both mail.yourdomain.com, where you replace.

So, for example, if your name is John and your domain name is mydomain.com:

Username: john@mydomain.com
Password: my-Secret-Password-2378
Incoming Mail Server: mail.mydomain.com
Outgoing Mail Server: mail.mydomain.com

In the Advanced Features for Outgoing Mail Server, there may be some additional settings that need changing.  Please make certain that:

  • You are using port 587 (ports 25 and 465 are no longer supported)
  • You are not using Secure Sockets Layer (SSL)
  • You are using Password for Authentication

We recommend using STARTTLS encryption.

What are the limits on my email accounts?

To protect our servers, we have placed limits on some email features, including the number of emails you can send, the size of your mailbox, and the file size of attachments.

Sending Emails

For emails you are sending, the limits are:

  • WebMail: 50 emails per day
  • Desktop client or device: 500 emails per hour, with 100 recipients per email
  • Website script that sends email: 1,000 emails every 12 hours
  • Mailing list: As many emails as you like, with 2,500 subscribers per list

We have a Zero Tolerance policy on users sending unsolicited email.  If our systems are deliberately used to send unsolicited email, we will suspend the user’s account.

Email Attachments

The limits on attachment sizes are:

  • Using WebMail: 2MB in total
  • Using a mail client or a device: 30MB in total

When you attach a file to an email, it increases in size, and even though the file may be smaller than the limit when you check its properties as a separate file, it may be over the limit when attached to an email. We also have no control over the limits set by other companies, who may have set their limits much lower – some even down to 2MB.

If you attempt to send an email attachment over your limit or your recipient’s limit, the email will be bounced back to you.

If someone sends you an email with attachments larger than 30MB, that email will be bounced back. The sender will receive a message informing them that the message size exceeds the size limit for your server.  You must then contact the sender to work out another way of sending attachments.

One way of sending large files to your recipient is if you both use Microsoft Outlook or Microsoft Outlook Express.  Certain versions of this software includes a ‘Break apart messages’ feature, where you can break an attachment up into sequential emails and they are recombined on the recipient’s computer.

Mailbox Size

The size of your mailbox will depend on which email package you have:

  • Standard Mailbox: 1GB capacity
  • Premium Mailbox: Initial 2GB capacity, but can be upgraded to 10GB in 2GB increments
  • Exchange Mailbox: 30GB capacity

If you use our WebMail or IMAP, this capacity includes all attachments and any emails you have in the ‘Trash’ but have not deleted.

If you are close to your 1GB mailbox limit, emails sent to you that would cause you to exceed your limit will not be delivered to your mailbox.  If you receive smaller emails, but not the larger ones, this could be what is causing that problem.

Please note: As part of our regular server housekeeping, any Standard Mailboxes that have not been checked for 100 days may be automatically deleted.

If your Standard Mailbox is too small, you can increase the capacity by upgrading to a Premium Mailbox. Your mail will be automatically transferred over, with no loss of data.

How can I connect to my mailbox with a secure connection?

We do support SSL encryption for all mail connection protocols.

If you are using our WebMail at http://webmail.yourdomain.com or http://www.outitgoes.com, you can access a secure version at https://www.outitgoes.com.

If you are connecting to your mailbox through a desktop-based email client, the ports are:

POP3: 995
IMAP: 993
SMTP: 465

Be certain to select the option in your mail client to use secure password authentication when using a secure connection.

You may receive a warning when making a secure connection to your mailbox. This is a common warning, and you can accept the certificate permanently despite the warning.

Email Access & Settings

The email server address for receiving email (both POP3 and IMAP) should be entered into your email software using the format mail.yourdomain.com and your domain name (without www. or any other prefix) should be used for the email username.

The outgoing mail server (SMTP) address is the same as the POP3/IMAP server address as shown above. Our outgoing SMTP service uses username and password authentication, so the outgoing SMTP Authentication option (not Secure Password Authentication or SPA) should be enabled in your email software if using our SMTP service for outgoing mail. The username and password to use is the same as your incoming POP3/IMAP email domain username and password.

Outgoing SMTP Email Port: Please ensure that you are using port 587. Ports 25 and 465 are no longer supported.

We recommend using STARTTLS encryption.

In many cases the email settings in your device can apply and set-up default email server settings with the details shown above.

Your Domain or Web Control Panel

Your Web or Advanced Domain Control Panel (provided with our Email Hostingcan be accessed using http://cp.yourdomain.com or https://ssl.extendcp.co.uk

This provides access to your email forwarding and web redirect for our free Control Panel access and with our Advanced Domain Control Panel this includes extras such as mailbox settings, email spam filter settings, email autoresponders, WebMail access, etc.

You can also change your passwords directly from the Control Panel.

What is SMTP?

SMTP (or Simple Mail Transfer Protocol), is a protocol for sending email messages between servers. Most email systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an email client using an email download protocol (usually either POP3 or IMAP).

In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the incoming mail (POP3 or IMAP) server and the SMTP server when you configure your email application.

SMTP now operates on port 587. The ports 25 and 465 are no longer supported. Our SMTP servers require authentication via SMTP AUTH, supporting the secure SSL/TLS.

We recommend using STARTTLS encryption.

What is a POP or POP3 mailbox?

POP (or POP3) is an early email protocol used to access mailboxes. It’s very simple and remains popular despite its age, however many users now find that IMAP meets their needs better. POP box is a term that is widely used but is not accurate, throughout our website you’ll find them referred to as ‘mailboxes’ or ‘mail accounts’.

What are the differences between POP3 and IMAP4 mail?

You may have noticed with your email software, and with our WebMail facility, that you are given the option of accessing your email through either POP3 or IMAP4.

These are two different protocols. With your email software, POP3 is downloaded directly from the mail server onto your device. Your device will store a “local copy” of the email, and usually delete it from the server. You can create local folders on your computer or device to organise the email, but you won’t see these or your email if you’re logged in using WebMail.

Additionally, if you create folders to organise your email in WebMail, you won’t be able to access these with your email software. Email will therefore only contribute towards the mailbox limits while it is left un-downloaded in the inbox.

IMAP4, in contrast, is left on the server (where it will continue contributing towards your mailbox limit). If you create folders/organise email with your email software, you will see this update when you log in to WebMail (and vice-versa). Similarly, when you mark a message as “read” in WebMail, it will appear “read” in your email software.

If you’re accessing your email on several different devices, IMAP is the most useful option. However, if you expect to receive high volumes of email, or want to be able to access your email offline, POP may be the better option as it will be downloaded and stored on your computer or device.

Why can I not send email?

Please note that ports 25 and 465 are no longer supported, so port 587 must now be used. The original information is included below for reference only.

 
 
It’s possible that your ISP (Internet Service Provider) is blocking port 25. Providers like AOL block this to prevent outside users from relaying bulk email off their servers. You should contact your provider to see if port 25 is blocked.

Otherwise you may have incorrectly entered details in your email software for the outgoing server (SMTP) for example, make sure you are authenticating the outgoing mail server as described in other support articles, or software on your device like anti-virus, firewall, Norton, Symantec, etc., is conflicting.

If port 25 is blocked, you could try using our alternative port 587 instead.
