I need some help. I have a Rails app on a VPS that connects to an
external SMTP server that can only send up to 250 emails per hour. If
I try to send the 251st email, it will just ignore it.
I almost bashed my head trying to setup sendmail so I can send my own
emails, but not all emails were being sent.
I basically want to send up to 250 emails immediately, and queue the
251st email til after the next hour since the max limit of 250 will be
reset. What can I use/install that does this for me? If I can avoid
installing postfix and sendmail or some other MTA program, it’ll be
way simpler for me.
