Did you mean concurrency limit (number of parallal deliveries) or rate limit (for example, number of deliveries per minute)? > Can postfix 'recognise' that recipientdomainA, recipientdomainB > and recipientdomainC are hosted at the same mail service provider > (bigmxprovider.com) so this limiting must be applied automatically? > > The destination is not immediately obvious by the recipient domain's > name and it would be enormous work to maintain such a list manually. You are sending multi-recipient messages, with some of those recipients in different domains that are hosted at the same email service provider. This should be possible but requires deep understanding of how Postfix works. It may be as simple as using check_recipient_mx_access with a FILTER action, or it may require a more subtle approach. Please let us know what you really need. To get an idea of the complexities, there is a thread that covers provider-dependent routing starting at https://www.mail-archive.com/postfix-users@postfix.org/msg91619.html The context is selective relaying through a content filter, but it could be tweaked to imnplement selective relaying through an email service providers.
