I'm trying to run a SimpleLogin instance on my raspberry pi 4 (aka armhf/armv7l) following the official instructions, but the resulting installation isn't able to send emails to my real inbox.

I installed swaks inside the docker container sl-app where all the to-the-real-inbox emails originates, after trying to send a message i got this error

$ docker exec -ti sl-app swaks --from "REDACTED" --to "REDACTED"
*** MX Routing not available: requires Net::DNS.  Using localhost as mail server
=== Trying localhost:25...
*** Error connecting to localhost:25:
***     IO::Socket::INET: connect: Connection refused

It can't connect to the postfix installed on the host system

$ sudo systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
   Loaded: loaded (/lib/systemd/system/postfix.service; enabled; vendor preset: enabled)
   Active: active (exited) since Wed 2021-12-22 19:11:26 GMT; 3h 10min ago
  Process: 21485 ExecStart=/bin/true (code=exited, status=0/SUCCESS)
 Main PID: 21485 (code=exited, status=0/SUCCESS)

The funniest thing is that a few days ago it worked just fine, the configuration hasn't changed but now it doesn't work anymore.

Any suggestions on how to resolve this issue?

As the systemctl status postfix shows, your postfix is not running. Run systemctl start postfix.

The message MX Routing not available is not related. It indicates that you don't have Net::DNS Perl module required by swaks installed on your system.

  • I tried `systemctl start postfix` but nothing has changes: emails don't get sent and `systemctl status postfix` is identical. I've also tried to backup everything and completely reinstall simplelogin but i still stuck to the same swaks error – Green and Blue g Dec 23 '21 at 17:35
  • You need to find out why your `postfix` is not running/starting. It is a separate question. Until this is sorted out any manipulations with `swaks` or `simplelogin` are meaningless. – AlexD Dec 23 '21 at 17:47
