- But the notification test emails from pfSense can only send if the 'Enable SMTP over SSL/TLS' box is unchecked so the emails are always sent in plaintext. My guess is that the Mail feature of pfSense has some configuration or compatibility issue with Office 365's TLS and STARTTLS features of its Relay Connector.

Office 365 is a cloud platform that businesses use for their day-to-day activities and make their environment more collaborative. The email server of Office 365, namely Exchange Online, is popular among enterprises. Office 365 end users configure their accounts on Outlook to access their mailboxes. The process is similar to web mail users configuring their email accounts like Gmail on email clients like Outlook, Thunderbird, etc. to access their mailboxes on their personal computers. While configuring web mail or Office 365 account on an email client like Outlook, users need to be aware of various settings such IMAP, POP, and SMTP with Office 365.
But, many people often don’t understand the configuration settings of IMAP, POP, and SMTP email servers. So, here we will talk about how SMTP, IMAP, and POP are different from each other, and what are settings of Office 365 and some popular email clients.
SMTP
Office 365 smtp settings What is Office 365? Office 365 is the brand name that Microsoft uses for a group of software and services subscriptions, which together provide productivity software and related services to their subscribers.
Known as Simple Mail Transfer Protocol – SMTP— is used for sending out emails from an email client like Thunderbird or Apple Mail to another email server. The primary function of SMTP is entirely different than that of IMAP and POP. SMTP is also used for relaying and forwarding emails from one mail server to another.
The SMTP uses port 25 by default, though it can also use port 587 and 465. The last was introduced as the port of choice for secure SMTP, which is still used by many mail service providers.
POP3
Known as Post Office Protocol – POP– is used for retrieving emails from a mail server to a mail client. POP3 is the latest version that is widely used by most email clients. It supports extensions and several authentication mechanisms. A POP client can retrieve emails in the following manner:
- Connects with the email server on port number 110 and 995 for SSL/TLS connections
- Retrieves email messages
- Deletes copies of the emails stored on the server
- Disconnects from the server
Also, POP clients are configured to enable the server to continue storing copies of the downloaded messages.
IMAP
IMAP is a more complex protocol, especially the current version IMAP4. The IMAP email clients are equipped with message flags that indicate whether messages are read, replied, or deleted. It even allows users to search against server mailboxes.
The IMAP email server works in the following manner:
- Connects to the email server with port number 143, and 993 for SSL/TLS connections
- Retrieves email messages
- Disconnects after email client app is closed
Note: The emails or messages in IMAP are not deleted on the server.
Configuring IMAP, POP, and SMTP in Office 365
Most users access their Office 365 account via Outlook or Outlook on the web. So, to add any account to Outlook, you’ll need information like the type of account, server names, and the SSL and port settings. Usually, you can get these settings from the email provider, but to make it convenient for you, we mentioned the server settings for most popular email providers along with Office 365.
Email Provider | IMAP Settings | POP Settings | SMTP Settings |
---|---|---|---|
AOL (Including Verizon.net) | Server: imap.aol.com Port: 993 Encryption: SSL/TLS | Server: pop.aol.com Port: 995 Encryption: SSL/TLS | Server: smtp.aol.com Port: 465 Encryption: SSL/TLS |

Consideration for Choosing Between IMAP and POP
Well, it’s hard to pick one among these for sending and receiving emails. So, many factors are to be considered while choosing between IMAP and POP3.
- Server Storage Space
- Access Anytime and Anywhere
- Synchronization
- Privacy
As IMAP leaves messages on the server; it consumes more storage space as compared to POP3. So, if your server is offering less storage space, then POP3 is a better choice.
IMAP enables accessing messages from multiple devices, which means if you have an iPhone, Android phone, a desktop, or a laptop, with IMAP you can read your emails from any of these devices.
Using an IMAP email server, you can achieve all the synchronization that a user needs with an email account, such as reflecting whatever action you performed on one device.
Privacy is a significant concern for almost every user. Such users often prefer to download all these emails and leave no copies behind on the server. For such users, POP3 is a better option to choose.

These options are enough to tell you which email server is a better option for you. However, if you want to migrate from an IMAP account to Office 365, then you’ll have to take help from a professional tool like Kernel IMAP to Office 365. This tool will help you migrate every single mailbox item from your IMAP account to Office 365.
More Information
This article explains how you can send email from devices and business applications when all of your mailboxes are in Office 365. For example:
- You have a scanner, and you want to email scanned documents to yourself or someone else.
- You have a line-of-business (LOB) application that manages appointments, and you want to email reminders to clients of their appointment time.
Option 1 (recommended): Authenticate your device or application directly with an Office 365 mailbox, and send mail using SMTP client submission
This option supports most usage scenarios and it's the easiest to set up. Choose this option when:
- You want to send email from a third-party hosted application, service, or device.
- You want to send email to people inside and outside your organization.
To configure your device or application, connect directly to Office 365 using the SMTP client submission endpoint smtp.office365.com.
Each device/application must be able to authenticate with Office 365. It can have its own sender address, or all devices can use one address, such as [email protected].
How to set up SMTP client submission
Enter the following settings directly on your device or in the application as their guide instructs (it might use different terminology than this article). As long as your scenario meets the requirements for SMTP client submission, the following settings will enable you to send email from your device or application.
Device or Application setting | Value |
---|---|
Server/smart host | smtp.office365.com |
Port | Port 587 (recommended) or port 25 |
TLS/ StartTLS | Enabled |
Username/email address and password | Enter the sign in credentials of the hosted mailbox being used |
Option 2: Send mail directly from your printer or application to Office 365 (direct send)
Choose this option when:
- Om namah geetanjali song free download. SMTP client submission (Option 1) is not compatible with your business needs or with your device. For example, your device or application does not meet the requirements of SMTP client submission, such as TLS support.
- You only need to send messages to recipients in your own organization who have with mailboxes in Office 365; you don't need to send email to people outside of your organization.
Other scenarios when direct send may be your best choice:
Pfsense Office 365 Smtp Setup
- You want your device or application to send from each user’s email address and do not want each user’s mailbox credentials configured to use SMTP client submission. Direct send allows each user in your organization to send email using their own address.Download firefox for mac os 10.6. Avoid using a single mailbox with Send As permissions for all your users. This method is not supported because of complexity and potential issues.
- You want to send bulk email or newsletters. Office 365 does not allow you to do this via SMTP client submission. Direct send allows you to send a high volume of messages.Note that there is a risk of your email being marked as spam by Office 365. You might want to enlist the help of a bulk email provider to assist you. For example, they'll help you adhere to best practices, and can help ensure that your domains and IP addresses are not blocked by others on the Internet.
Option 3: Configure a connector to send mail using Office 365 SMTP relay
This option is more difficult to implement than the others. Only choose this option when:
- SMTP client submission (Option 1) is not compatible with your business needs or with your device
- You can't use direct send (Option 2) because you must send email to external recipients.

SMTP relay lets Office 365 relay emails on your behalf by using your public IP address (or a certificate) to authenticate Office 365. To do this, you'll need to set up a connector for your Office 365 account, which is what makes this a more complicated configuration.
