erics, March 17th, 2022 When I sent email from my desktop Mac cron jobs, it went out with the full hostname as the domain, i.e.: root@demo.wyzaerd.com, when all I wanted was a simple root@wyzaerd.com for ease of deliverability and domain maint. Edit the mail configuration file main.cf:
|
1 |
vi /etc/postfix/main.cf |
Add/edit the myorigin value of $mydomain:
|
1 |
myorigin = $mydomain |

erics, July 16th, 2021 PROBLEM: Email delivery to Google was failing with a “Service Unavailable” error:
|
1 |
relay=aspmx.l.google.com. [IPv6:2607:f8b0:400d:c0c::1a], dsn=5.0.0, stat=Service unavailable |
Note that the network address for the destination is shown as IPv6! That is the root cause of the issue: 1. Sendmail is sending mail from the IPv6 address instead of the IPv4 address 2. Google rejects IPv6 senders without proper reverse […]
