@Rol-a For some reason, it looks like letsencrypt failed to generate a certificate for your domain. Look if there is something in /etc/letsencrypt/live/mail.manox.io/ folder. If not, try to run certbot manually. |

Thanks @tonioo. Yes, I am struggling with this letsencrypt certificate. I still haven't been able to get it to work, but I am planning on rebuilding everything. Hopefully it goes well. I will update if I figure what the real issue was. Thanks again. |

Your certificate is broken or the folder location is wrong. Try to renew it and use the letsencrypt parameter to generate a RSA key to be sure that it works. |

Thanks, that's already where i had been looking because the issue happened after I renewed the certificate. The thing was that letsencrypt deprecated the previous method I used when I was first installing modoboa so I went with their nginx + pip option. So I believe that's what may have changed the paths. |

Hello there!
First and foremost, thank you very much for this wonderful tool and everything you guys do. It doesn't go unnoticed.
I've been getting an issue lately to send out emails. This started to occur after I added more domains to modoboa. My assumption is that the issue is related to the Let's Encrypt SSL certificate because I had the issue once before after I reinstalled Let's Encrypt due to a change on their website. I ended up fixing it somehow. This time however, I am having all kind of trouble fixing it. Here is the error I am getting from the log
Jul 11 12:16:04 mail dovecot: imap-login: Error: Diffie-Hellman key exchange requested, but no DH parameters provided. Set ssh_dh=</path/to/dh.pem Jul 11 12:16:06 mail dovecot: imap-login: Error: Diffie-Hellman key exchange requested, but no DH parameters provided. Set ssh_dh=</path/to/dh.pemI can also provide few lines from the mail log if needed.Any pointer will be greatly appreciated. Thank you very much.
