Sending Mail Doesn't work

#1
Within ols-docker-env the WordPress sites, mailing function does not work at all.
I have already "Postfix" installed on my host, So how it's possible to docker environment use the SMTP server on host to sending mails?
I tried to set my IPs from this post, but it does not work either.
Would you Kindly suggest proper solutions to bypass this issue


Thank you ALL
