Email Configuration (SMTP)

The ABCD OPAC requires a working email configuration to interact with users. This includes sending Password Recovery links, Reservation notices, and Comments/Suggestions to the library staff.

Access: OPAC Configuration > Email Configuration (adm_email.php)

1. Configuration Parameters

This interface generates the opac_conf/correo.ini file. Configure the fields according to your email provider (e.g., Gmail, Outlook, or institutional SMTP).

Field	Description	Example
Server (Host)	The hostname of your SMTP provider.	smtp.gmail.com
Port	The network port for sending mail.	465 (SSL) or 587 (TLS)
User	The full email address used to authenticate.	library@university.edu
Password	The password or App Password for the account.	********
From (Email)	The email address that will appear as the sender.	no-reply@library.org
From (Name)	The human-readable name of the sender.	Central Library System
Subject	Default subject line (often overridden by specific scripts).	Library Notification
Test Recipient	Email address to receive a test message upon saving.	admin@library.org

2. Connection Settings

Mailer Type

You must choose the mechanism for sending emails:

• PHPMailer (Recommended): Uses the external SMTP server configured above. This is the most reliable method and prevents emails from going to Spam.
• PHP Mail: Uses the local server's internal mail system (sendmail). This often fails if the server is not properly configured as a mail relay.

Security (Encryption)

Select the encryption protocol required by your provider:

• SSL: Typically used with port 465.
• TLS: Typically used with port 587.
• None: Used for internal servers (port 25).

Gmail Users

If you are using Gmail, you cannot use your regular login password. You must enable 2-Step Verification and generate an App Password. Use that App Password in the "Password" field.

3. Testing the Configuration

To verify if your settings are correct:

1. Fill in all the SMTP fields.
2. Enter a valid email address in the Test Recipient field.
3. Click Save.
4. The system will attempt to connect and send a test email immediately. Check your inbox (and spam folder) for a message.

4. Technical Details (correo.ini)

The configuration is stored in a standard INI file located at: bases/opac_conf/correo.ini
