DreamHost POP, IMAP and SMTP settings with Port Numbers

While setting up a custom email on a hosting server, you need the right setup – like dreamhost email settings. Then you can forward it to any other mail of your choice. But most computer users would like to use it with an email client like Outlook, Mailbird, Spark, Postbox etc.

Though email is old fashioned in 2022, it is still one of the most powerful ways of marketing. Business and Professionals still use email to communicate with each other on relevant matters. For this purpose, they need to send and receive emails.

If you are using dreamhost email hosting to host your email addresses, then you need some protocols to download and send emails in Outlook etc. For receiving email you need either POP or IMAP. To send an email, you need SMTP.

Settings need to be correct if they need to work correctly with the DreamHost server. Port numbers are taken by default for certain email clients, while you need to change them based on security or insecure protocols.

Since each email client is different, we’re providing the general POP, IMAP, SMTP settings with their required port numbers. This is a quick reference that becomes handy during email configuration.

DreamHost POP Settings

Based on your decision to use POP or IMAP, choose the corresponding port number below. Once again, secure IMAP is recommended.

  • POP3 | Port 995 (Secure Transport   — SSL function enabled)

Other options

  • POP3 | Port 110 (Insecure Transport — No SSL function enabled)

DreamHost IMAP Settings

  • IMAP | Port 993 (Secure Transport   — SSL function enabled)

Other options

  • IMAP | Port 143 (Insecure Transport — No SSL function enabled)

DreamHost SMTP Settings

Simple Mail Transfer Protocol (SMTP) is the de facto standard for outgoing email transmissions across the Internet.

  • SMTP | Port 465 (Secure Transport — SSL function enabled)
  • SMTP | Port 587 (Insecure Transport, but can be upgraded to a secure connection using STARTTLS)
  • SMTP | Port 25 (Outdated and not recommended. username/password authentication MUST be enabled if using this port.)

Port 465 with SSL is recommended, however some email clients are unable to use this port.

If you are unable to use port 465, the next best option is port 587 using STARTTLS.

DreamHost Outlook Settings

The Server Information should be the following
a. Account Type : IMAP (DreamHost prefers it this way)
b. Incoming mail server : imap.dreamhost.com
c. Outgoing mail server (SMTP): smtp.dreamhost.com

Check the option that says “Require logon using Secure Password Authentication (SPA)“. Then click on “More Settings“.

pop and imap account settings outlook

The “Internet E-mail Settings” window will open.

DreamHost Incoming and Outgoing Servers with Port Numbers

1. On the “Outgoing Server” tab, check the option that says

– My outgoing server (SMTP) requires authentication

2. On the Advanced tab, the following should be changed.
a. Incoming Server (IMAP) : 993
b. Outgoing Server (SMTP) : 465

For both of them the option that says “Use the following type of encrypted connection” should be SSL.

Then click “OK“.

On the main window, click on “Next“.

The same email acccount with DreamHost IMAP details is created in Outlook.

You should see something like mail@customdomain for this account.


As we can see above it is very easy to setup email in Outlook, if you have the right mail settings at hand. I was able to test a sample email account with some trial and error. If you don’t check the SSL option or use the right port, your email may not work.

The top DreamHost review about its features, plans, pricing and pro services can be seen here.

So I recommend you to use the above combination of DreamHost and Outlook for easy configuration.

  1. Thx for this help.
    Still have trouble with ports and settings. I am attempting to set up Outlook as client.
    Note this contradiction re SPA:

    (i) Dreamhost advice {https://help.dreamhost.com/hc/en-us/articles/115001316792-Outlook-Configuring-email-with-Outlook-on-Office-365}

    (ii) you (WPreview)do not explain but in your image above the SPA box is checked.

    (iii) mailbird.com, regarding Dreamhost specifically, provides an image where SPA is unchecked. { cf. https://www.getmailbird.com/setup/access-dreamhost-com-via-imap-smtp#outlook}

  2. This tip re : was useful. It worked for me (on Outlook 365 / Windows 11) and resolved the failing advice direct from Dreamhost
    Thx !

    Note, however, that the manual adding of an account on Outlook 365 ( I mean MS Office program, not Web Outlook, if that is what you meant here).. does not produce the layout that your image above shows (cf. below the phrase

    The layout one arrives at in MS Office 365, under Account / “Server Settings” does not have ” More Settings.” The options are constrained to these items:

    Incoming Outgoing
    Protocol IMAP SMTP
    Server imap.dreamhost.com smtp.dreamhost.com
    Port 993 587

    SPA (leave blank) (leave blank*)

    * re SPA for outoging: Outlook should do something automatically, so that later, when you return to this screen, you see checked thes secondary boxes: ” SMTP requires authentication” and “use same settings as my incoming mail server”

    Thx — hope you can refine your notes even more !
