How to Configure Joomla 2.5 to Send Email Using SMTP

Joomla 2.5 has reached its end of life as for 12/31/2014. Please be advised this may be a security risk to your website. You can view more information about the end of life here.

By default, Joomla 2.5 uses the php mail() function to send emails from the server. At InMotion Hosting, our servers support the php mail() function, however not all servers have this enabled. If you are not hosting with InMotion Hosting and your server does not support the php mail() function, you can configure Joomla to send email using SMTP.

This method is also a good way to resolve the Could not instantiate mail funtion error. Using SMTP to send email requires that you have a valid email address, so if you haven’t already, be sure to create an email address.

To configure Joomla 2.5 to use SMTP:

  1. Log into your Joomla Dashboard
  2. In the top menu, hover over Site and then click Global Configuration
  3. Click the Server tab
  4. Under Mail Settings, configure the following settings and then click Save:
    MailerSet this to SMTP
    SMTP AuthenticationSet this to Yes
    SMTP Security
    SMTP Port
    If your SMTP server uses SSL, select this option from SMTP Security and then enter the SSL Port required for your SMTP server
    SMTP UsernameEnter your SMTP Username, which generally is your full email address
    SMTP PasswordThis will usually be your email address’ password
    SMTP HostIf your email account you’re sending email from is on the same server as your Joomla 2.5 site, use “localhost” here. Otherwise, enter your SMTP hostname here.

  5. Congratulations, your Joomla 2.5 website is now configured to use SMTP! Be sure to test your site and ensure emails are sending properly. We tested this by signing up for new users within Joomla and monitored the email notifications sent to the administrators.

    1. Hi,

      I’m sorry to see that you are receiving an SMTP Error. This indicates that the settings for the SMTP server are not correct. I recommend verifying those settings and if they are all correct, you may need to check your server to ensure that it is configured for SMTP functionality. I hope this helps!

    1. Hello Eka,

      Be sure to test the usrname and password via webmail. If it is still giving the error, you may want to contact Live Support if you are one of our customers so they can check out the email logs to see if there is anything amiss there.

      Kindest Regards,

    1. Hello Samuel,

      Compare your settings with the ones in the image above. I would make one exception however and change the port from 25 to 587 if it does not work right away.

    1. Hello Rupesh,

      If you are unable to login to your administrator, you can edit the configuration.php file and then add the SMTP settings for your email, if you Joomla admin is set to use SMTP to send emails. Otherwise, you will need to manually change the Joomla password through the database.

      I hope this helps to answer your question, please let us know if you require any further assistance.

    1. Ensure that your message is being successfully authenticated using SMTP and has the correct credentials. Without the correct SMTP credentials, the message will fail to send.

  7. Hi,

    I am running my website on Joomla 2.5 configured to use the PHP Mailer and a month ago something very unusual happened whereby multiple copies of the same email message were being sent out to users. Email messages are automatically sent out when a user registers or post a task etc. confirming to the user their action.

    Have anyone experienced such issue whereby multiple copies of the same email message are sent out to the same users and how to resolve this?

    1. Hello Kenneth,

      You are the first person who has reported this issue so far. If it happens again, please , contact our Live Support as quickly as possible so they may investigate the server email logs to see if/why multiple emails were sent out.

      Kindest Regards,

    1. Hello cool boy,

      Thank you for contacting us. If your emails are being flagged as spam, using SPF records and Domain Keys can help identify which machines are authorized to send email from your domain(s).

      Also, I recommend reviewing our guide on common words that trigger spam filters. If you include these terms, it can result in getting flagged as spam.

      If you have any further questions, feel free to post them below.
      Thank you,

    kindly suggest what need to be done my email setting as below 



    1. Hello Atuel,

      Thank you for contacting us. This means that your SMTP settings are correct, since email is being sent from Joomla successfully; but Google is flagging it as spam.

      I recommend reviewing the link Google provided to their Bulk Senders Guidelines, to make sure you are within their guidelines.

      Also, setting up SPF records and Domain Keys can help identify you as a valid server for sending email.

      If you have any further questions, feel free to post them below.
      Thank you,


  10. Hello,

    thanks for quick replies. 

    Now I set a gmail account.

    If I turn off Authentication I get a Google error: Authentication required.

    If I set Security SMTP to none I get a Google error: must TLS before.

    If I set [email protected] I get no errors and no mails.

    Any suggestion?

    Thanks in advance,


    1. Hello Alberto,

      If Google is forcing TLS then you will want to use that but change the port number. 25 is reserved for non-secure. 465 is the normal port number for TLS-SSL. Give that a try.

      Kindest Regards,
      Scott M

  11. Hello,

    I have no errors selecting PHP Mail or SendMail, but I don’t receive any email with these settings.

    Setting up


    email: the same as administrator [email protected]

    Sender: the name that will be displayed (not an email)

    Authentification: Yes

    Security SMTP: TLS

    Port SMTP: 25

    SMTP User: the same as administrator [email protected]

    Password SMTP

    SMTP Server:


    It prompt the error

    SMTP connection failed and no mail is sent. Any suggestion?



    1. As you’re using port 25, you’ll want to have the Security option turned off. As you are using hotmail’s servers, I don’t have much information on what may be going on when connecting to them, so you may want to contact their support for more information.

  12. Hi,

    I selected TLS but now it says SMTP Connection Failed.

    If I select PHP Mail or Send Mail no error is prompted, but I can’t receive the mail at the selected address. 

    If SMTP is the sender where may I select the receiver of the mail?

    Thanks in advance,


  13. Hi,

    I tried to follow these instructions but I still get the same error:

    La siguiente dirección de destinatario ha fallado: [email protected] : MAIL not accepted from server,530,5.7.0 Must issue a STARTTLS command first. m3sm3308297wik.7 – gsmtp
    Error del servidor SMTP: 5.7.0 Must issue a STARTTLS command first. m3sm3308297wik.7 – gsmtp
    Error del servidor SMTP: 5.7.0 Must issue a STARTTLS command first. m3sm3308297wik.7 – gsmtp

    I need help, please. Thanks in advance,


    1. Within the mail settings in the SMTP Security dropdown, select TLS. It should then begin working correctly.

    1. We have tested the instructions and they do indeed work correctly in Joomla 2.5. Could you clarify what specific step you are having issues with?
