Yahoo Mail IMAP and SMTP settings
Incoming and outgoing server, port, encryption and password requirements — everything a mail client asks for.
Incoming mail (IMAP)
- Server
- imap.mail.yahoo.com
- Port
- 993
- Encryption
- SSL/TLS
Outgoing mail (SMTP)
- Server
- smtp.mail.yahoo.com
- Port
- 465
- Encryption
- SSL/TLS
An app password is required
In your Yahoo account, go to Account Security and generate an app password for IMAP access.
Yahoo Mail always requires an app password for IMAP access once two-step verification is enabled; the regular account password is rejected in that case.

How it works
- Enter your email address — or just your domain. No password is asked for: this page connects to nothing.
- We identify your provider — first from the domain if it is a known one (gmail.com, orange.fr, free.fr…), otherwise by querying your domain's DNS records to recognise the host behind it.
- Copy the settings into your software — incoming IMAP server and outgoing SMTP server, with the port and encryption type, plus whether an app password is mandatory.
Use cases
- Setting up a mailbox in Thunderbird, Apple Mail or Outlook — when the client's automatic detection fails and it asks for the servers by hand.
- Preparing a transfer or a backup — our transfer, backup and analysis tools ask for exactly these IMAP settings.
- Understanding why a connection is refused — nine times out of ten it is a port that does not match the chosen encryption, or a missing app password.
- Configuring sending for a website or an application — the SMTP settings listed here are what a contact form or an invoicing tool expects.
- Finding a domain's servers on shared hosting — DNS detection often surfaces the real server name behind your domain.
What this tool doesn't do
- The tool does not test the connection: it gives you settings, it does not check that they work with your credentials. The mailbox tester does that job in seconds.
- It never asks for a password, and does not need one. Be wary of any site that demands your credentials in order to give you a port number.
- For an unknown domain, the suggested servers are hypotheses deduced from DNS and from naming conventions, not the truth: only your host can confirm.
- POP3 settings are not listed: all our tools, and nearly all modern usage, go through IMAP.
- Proton Mail exposes no direct IMAP: you have to go through the Proton Mail Bridge application installed on your computer, as the provider page explains.
Frequently asked questions
What is the Yahoo Mail IMAP server? +
The incoming mail server is imap.mail.yahoo.com, port 993, SSL/TLS encryption. It is the server your email client queries to read messages and folders.
What is the Yahoo Mail SMTP server? +
The outgoing mail server is smtp.mail.yahoo.com, port 465, SSL/TLS encryption. It is the server that sends your outgoing messages.
Do I need an app password for Yahoo Mail? +
Yes. In your Yahoo account, go to Account Security and generate an app password for IMAP access. Yahoo Mail always requires an app password for IMAP access once two-step verification is enabled; the regular account password is rejected in that case.
The connection to Yahoo Mail fails — what should I check? +
Check the host spelling, the port and the encryption, then the expected password (regular or app password depending on the provider). The fastest route is the free IMAP tester: it actually connects to the mailbox and tells you whether the server, the port or the credentials are blocking.
