Thanks for the tips! I've specified the ip addresses which are allowed to send.

A question about mynetworks

I've added my local ip adress range to allow computers in my lan to send e-mails though my local postfix server. Is this the correct setting to achieve this? And am I correct that with the current mynetworks configuration only clients in my lan can user the smtp server? According to mxtoolbox I d

Hi, Most of my mails are delivered and send without problems. However some domains reject e-mails with the error message below. What can I do to fix this? Is this a DNS error? Or a postfix config problem? Thanks in advance! <>: host mxb.mail.widexs.nl[213.206.122.196] said: 550-Verification

Re: What is the proper way to deal with non-existing e-mail addresses?
