Integrate Pepipost With vBulletin

Relying on the PHP internal mail function has always caused problems with a few configurations for vBulletin. vBulletin supports sending email over SMTP. The SMTP server options can be edited via the Email Options in the vBulletin Options, which will be enabled via the SMTP Email switch.

This integration guide will review the process of enabling SMTP for the Pepipost mail service of your vBulletin forum. Following these steps will ensure properly delivered emails from your website to users and a high inbox rate.

Step 1:

Here you can setup everything related to how your forum sends and handles email.

Enable Email features? – Enable the following email-sending features: Report Bad Post, ‘Contact Us’ Link, Email a Member, Email this Page to a Friend, New Post Notifications to Members

You can turn off the ‘Send to Friend’ feature for individual user groups in the User Permissions area.

Allow Users to Email Other Members – Allow users to send emails to other users. Use the option below to determine how the emails are sent.

Use Secure Email Sending – If ‘Allow Users to Email Other Members’ is set to ‘Yes’, how should members’ email addresses be displayed? If this is set to ‘Yes’, then an online form must be filled in to send a user an email, thus hiding the destination email address. Setting ‘No’ will mean that the user is just given the email address in order to send email using their email client application.

Email Flood Check – Specify in seconds how much time must elapse before a user may send consecutive emails. Set to 0 to disable this flood check.

Use Mailqueue System – When enabled, subscription emails generated by your site will be processed in batches to lessen the load on your server. Account activation, lost passwords and other vital emails are sent instantly regardless of this setting. If your site has low traffic, subscription emails may be delayed.

If you have a large site, you may wish to enable locking. This prevents a rare situation where the same email is sent multiple times.

Number of Emails to Send Per Batch – vBulletin includes a mail queuing system to prevent bottlenecks when sending lots of email. Use this option to specify how many emails will be sent per batch.

Bounce Email Address – The email address where bounce messages will be directed. If this field is blank, the Webmaster Email address will be used. This email is used when using an SMTP server, or when the ‘Enable -f Parameter’ email for sendmail is switched on.

Enable “-f” Parameter – Some sendmail servers may require the “-f” parameter to be sent with email calls from PHP. If you are having problems with users not receiving email, try enabling this option. In all likelihood, your problem will not be caused by this setting.

SMTP Email – Set this option to yes to use a SMTP server rather than the internal PHP mail() function.

SMTP Host – Please specify the host as

SMTP Port – Please specify the port here. Port can be 25, 587 or 2525. Most of the shared hosting providers block these port to protect their network from spamming. Hence, if even after doing all the setup, your emails are not getting delivered, then try contacting your hosting provider to unblock these port for outgoing SMTP connection.

SMTP Username – Please specify your Pepipost’s username here.

SMTP Password – Please specify your Pepipost’s password here.

SMTP Secure Connection – If you’ve enabled SMTP mail and your server requires a TLS connection, please set this to yes. This requires OpenSSL support to be compiled into PHP. To get started you can keep it off.
