zoho SMTP settings

SMTP stands for Simple Mail Transfer Protocol. Using this, you can send mails from an email application via a specific server.

It’s used to send mails through another email client via your Zoho Mail account by configuring the settings in that client with Zoho's SMTP information.

For Personal users

Personal users are individual users with an email address that has a username, such as marldaniel@zoho.com

Outgoing Server Name: smtp.zoho.in

Port: 465

Security Type: SSL

Require Authentication: Yes.

For Organization users

Organization users are those who have a domain-based email address, such as markdaniel@yourdomain.com

Outgoing Server Name: smtppro.zoho.in

Port: 465 with SSL or

Port: 587 with TLS

Require Authentication: Yes

 

The email address should match the email aliases/ email addresses of the account for which the authentication details are given.

Zoho Mail SMTP Configuration Settings - TLS

Outgoing Server Name: smtp.zoho.in

Port: 587

Require Authentication: Yes.

The address must match the account's email aliases/ email address, for which the authentication details are provided.

If you have enabled Two-Factor Authentication, you may require an Application-specific Password to set up the account on other devices.

Troubleshooting Settings for SMTP Server

Duplicate Sent Email Copies

When you send mail from other ISPs like Outlook, Hotmail, Gmail, or any other email clients using smtp.zoho.in, those sent emails get saved in your Sent folder automatically.

But, sometimes, some ISPs save a copy in the local Sent folder by behavior. This results in duplicate emails in the Sent folder. One is the mail saved by the email client, and the other one is by the Zoho Servers. In such cases, the user can choose the option “Do not save a copy in the Sent folder” to avoid 2 copies of every message. ​

➡️ Login to Zoho Mail

➡️ Go to Settings ​

➡️ Navigate to Mail Accounts and click the respective address from the left listing.

➡️ Under the SMTP section, uncheck the 'Save Sent Mail Copy' to not save the mails sent using the smtp.zoho.in configuration in the Sent folder.

Unable to Connect to Outgoing/ SMTP Server

Sometimes, ISPs connect to the default port 25 when connecting to the SMTP server. In the case of Zoho Mail, you need to connect to smtp.zoho.in in SSL or TLS ports i.e 465 or 587 respectively.

For example: In Outlook, you need to check the 'Advanced Server Settings' section.

However, if the port details are correct but there are still issues in connecting to the server, you need to get the traceroute details for smtp.zoho.in server and share it to support@zohomail.com.

Don’t forget to provide the details of your account, your email client, and the necessary screenshots of the configuration, etc.

Authentication Failure

When configuring SMTP/ Outgoing Server, you need to provide the address and the correct authentication password.

If you have enabled Two-Factor Authentication, you may require an Application-specific Password to set up the account on other devices.

Relaying Disallowed Error

You will see a 'Relaying Disallowed' error while sending an email if the login credentials (the address) you have provided in the application do not match the credentials (the address) of your account's outgoing server.

The SMTP client will fail to send the mail because of the mismatch of the credentials.

It can also happen if a mail address is wrongly spelled while configuring your email inbox or used as default in a coded program.

You need to correct the mail address provided to resolve the 'Relaying Disallowed' error.

Relaying Disallowed Error while Using Outlook Calendar and Mail

Outlook tries to send mails with the “From address” as Organizer's email address when a user tries to forward 'Calendar Events' directly from Outlook. In such cases, you will see the 'Relaying Disallowed' error.

You can’t forward the invitation directly because the addresses don’t match when you send the invite.

Instead of this, you can right-click the event and choose the option of 'Forward as Attachment' to send the event invitation.

Not Receiving Emails from Website Contact Forms

The Submit option in ‘Webforms’ or 'Contact us' forms of a website is typically used to send mails. Your Website Hosting Provider (Web Host) triggers these mails.

Mostly the website's domain name matches the address, as the address is based on the domain name.

For instance, www.yourdomain.com/contact.html page will submit the details of contact@yourdomain.com.

In such cases, the Web Host or email server assumes that the mails should be delivered locally as the domain name is the same and triggers the mail wrongly.

How to Fix

Open the WebHost settings

⬇️

Click on the “Remote Email server option” and denote that these emails should be delivered externally

⬇️

Check for any Local Email Delivery configuration and switch off the WebHost's local setting.

Such measures will ensure that emails from webforms or contact forms reach the Zoho Mail servers and are delivered to the correct email accounts.
