sl installed and working but no verificationmail sent

[swoop124]

Hello everyone,

I installed Simple-Login, following the doc, on this github, step by step. I'am able to send Mails from the Dockerhost via swaks but simple-login doesn't send the verifivation mail from registering. In the mail.info log i can only see this:

 /opt/sl# tail /var/log/mail.info

There are some other lines in the config file but they are all commentet out.

telnet from ths sl-app container to postfix on host is connecting fine.

Did i miss something? I don't get it. For me it looks good, sl-app seems not to send the verification mail or i have it missconfigured and it sends it to nowhere, but schouldn'n there be some errormessages?

please help.

oh, btw in the future i would like to use a relayhost for outgoing and incomming mails is that possible?

regards

i saw the mails html code, that schould be sent as e-mail, in the sl-app container-logs.

What does that mean?

For everyone who stumbles about this problem!!

After about two hours testing i am now certain that it is working now!!!!

i think the problem was this configfileentry:

# Only print email content, not sending it, for local development
NOT_SEND_EMAIL=false

I komm the 2nd line out and restartet all containers. After about ten fifeteen minutes it began to work.
