Hi Bob,
Just to make sure I understand you: Some app is sending emails to
ord...@example.com at the rate of 1000 per second, and another app is
fetching email from ord...@example.com to process them?
Hello,
Actually, thousands of customers would send order emails to a system
running postifx. All orders end up in ord...@example.com. Then,
another app fetches these emails via Dovecot (POP or IMAP), ideally at
the rate of 1000 per second.
I think it might be difficult to accomplish this via POP since I think
Dovecot would have to lock the account while doing the POP downloads.
This makes it difficult to have more than one app downloading at a
time.
Cheers,
Bob
Don't use POP3 or IMAP; instead deliver the messages to a command. For
example, GNU Mailman is mailing list software which pipes each incoming
list message to a Python script. That command can then perform the
necessary processing.
I don't know what you had in mind, but if the messages can be handled
independently, it's easy to add new machines. Just duplicate the config
on another box, and create an MX record for it.
