[pfx] relaying with oAuth

Hi All, We are relaying emails to Microsoft SMTP servers with basic authentication but Microsoft is sunsetting this form of auth and they push everyone to oAuth. I'm curious what do you use for oAuth? I've found a github project and I'm about to give it a try very soon but I'm open to any viab

[pfx] managing multi instances

Hi, I have two questions regarding multi instance management. 1. is there a way to batch migrate multi instances from serverA to serverB? We are planning to replace our servers and I'd spare as much manual work if possible. 2. is there an ad-hoc way to move mails between instances by their qu

Hi, I'm wondering why is the qmgr process count set to 1 by default in master.cf Does it make any sense to increase this number to 2 or 5 or 10? There are a couple of million emails are going through our servers per day and there is a plenty of free CPU and RAM which could be used. Also I'm

[pfx] destination based rate limiting

Hi, How can one set up outbound rate limiting for a certain mail service provider? 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 destin
