First thank Webinoly for its existence.

But I have problems with the functioning of the default mail server.

When I installed Webinoly and wanted to reset the wordpress password, the mail server was not working. I have read the previous forum queries related to SMTP but I have not been able to solve it. I have tried reinstalling postfix, installing mailutils and configuring the DNS but it has not worked. It's Ubuntu 18.04 and the firewall is ok.

Then I have a couple of doubts:

1.- After installing Webinoly by default. Should postfix be able to send emails? (At least to reset passwords in wordpress)

2.- After doing sudo "log -email" shows:

Is this normal?

Thanks and best regards.

  1. Yes.
  2. No, it's not normal.
Also, you should not manually reinstall packages, that's what Webinoly is for.

Thanks for the reply and sorry for the delay.

I think that one aspect that I did not take into account is that to receive emails in certain emails you have to do it through port 587 and TLS.

A greeting.
