If it is only a small volume, I would especially stay with a proven and implemented solution for the MTA instead of rolling my own in a week or two. If your clients are well-behaved, they might queue the status mails themselves and retry after some time so you get a chance to fix your code.

Consider that you can set up the MTA to forward all mail to a Perl script anyway through a .forward file. I would avoid the risk of introducing an unproven component. The mailserver handles queueing and the complete protocol for you - why put that hassle on yourself if the usage is only 300 mails per day?
