However mails to any other domains received after an hour delay.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its because there is no value set for slow_destination_rate_delay in postfix configuration. So we need to set it as 1s in main.cf file<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Solution:<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Edit \/etc\/postfix\/main.cf and add below line<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">slow_destination_rate_delay = 1s<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Save the file and restart postfix<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">\/etc\/init.d\/postfix restart<\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Now you should be able to receive mails immediately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Note: <br>If you are recieving mails at spambox, please make sure that you have proper SPF and rDNS records are setup for your source server. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks for using&nbsp;<a href=\"https:\/\/pheonixsolutions.com\/\">pheonix solutions<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You find this tutorial helpful?
