Dec 19 19:55:41 server postfix/smtp[30050]: IDXXXXXXXX: to=email@deliveryaddress.tld, relay=deliveryaddress.tld[000.000.000.000]:25, delay=470, delays=469/0.1/0.28/0.79, dsn=4.0.0, status=deferred (host deliveryaddress.tld[000.000.000.000] said: 451 mail rate limit exceeded – try again later (#4.3.2) (in reply to end of DATA command))
Basically I’m fine with the server delaying sending, but it needs to accept the messages into the queue.
Can this be done, or can I just remove the rate limit?
Assuming of course that the outgoing mail server is the issue here, as my client crashed after sending around 360 out of 500 emails in its queue. This is a perplexing number as I can’t see that anywhere in any configuration.
