Check the vBulletin Options - Email Options. If you have selected the option 'SMTP Email' to send through an SMTP server, rather than using the internal mail() function, you can set the mailbox for bounced messages in the option 'Bounce Email Address', where the default value is set in the option 'Webmaster's Email' from 'vBulletin Options' - 'Site Name / URL / Contact Details'.

If you have not selected 'SMTP Email', your forum uses the internal mail() function. In the Windows server environment the sender of the email messages is specified in the PHP setting 'sendmail_from' in the file php.ini and then that sender is used as the return address by the servers bouncing the messages.

If your forum is in a *nix environment with a sendmail server, you can probably set the option 'Enable '-f' Parameter' and then use the option 'Bounce Email Address'. Hopefully someone who uses this combination can confirm the settings.

You need a separate mailbox to monitor the messages that bounced because of incorrect email address, mailbox over quota or temporary connection problems.

Auto-replies from holiday rules are different because they are delivered straight to your main mailbox for the forum. Depending on your mail server, you may able to filter them through rules available for example in MS Exchange. If you cannot block auto-replies because the subject does not contain particular words like 'out of office' or 'on leave' or the subject is in a foreign language and if you happen to use the old format in EI Mod, you can implement my hack to delete duplicate messages from the mailbox before they are broadcast to the members: https://vborg.vbsupport.ru/showpost....&postcount=953
