Hello ,
first of all thank you for posting here.
i am new to powermta i would appreciate if you could advise me what’s
the best optimal configuration for performance / speed
the target is to send more but keep connection low not to be banned
thank you in advance here is my config:
max-smtp-out 20 # max. connections *per domain*
bounce-after 1m # 4 days, 12 hours
retry-after 10s # 10 minutes
max-msg-rate 100/h
max-msg-per-connection 20
max-errors-per-connection 10
smtp-greeting-timeout 5m # added in v3.2r17
mx-connection-attempts 30000 # added in v3.2r16
smtp-pattern-list backoff
backoff-to-normal-after 2h # added in v3.5
backoff-max-msg-rate 50/h # Use with PowerMTA 3.5
backoff-retry-after 90m
dkim-sign yes
ignore-8bitmime true
You need to create rules for every domain (esp) , because every one of them have different policies. Example: domain google,com :
max-msg-rate 100/h
max-msg-per-connection 20
max-errors-per-connection 10
domain yahoo.com:
max-msg-rate 50/h
max-msg-per-connection 10
max-errors-per-connection 5
STart as low as possible and then after every warmup check the messagge queue to see who need to be lower or higher. Is not easy to get ip warmup if you push beyond limits because you can get blacklisted 100%.
