Delaying mails and losing attachment files

Hi,

This isn’t a bug actually but I have a problem and maybe you can help me.

I’m using a plugin (mailer) in order to delay emails for not to reach the smtp limit of my provider. Each five minutes, a small amount of emails are sent and so, I’m able to send about 2000 emails per day without problems. The plugin makes a txt file in a temporary folder per each email it has to send, then it takes these files in chronological order and send them via smtp.

The problem is that attached files in contact form 7 are saved in a temporary folder only for seconds, and when mailer plugin makes the txt file, Contact form 7 puts the email as sent, and so, when the email is actually sent, attached files have already been deleted from the temporary folder.

I’d like to set the time that attached files are going to be in this temporary folder in order to they “wait” for the email is sent before files vanishes.

Is it possible?

Thanks.
