Ok, I've looked around and looks like it is possible to add an argumento to generate SAN SSL certificates. But i have one doubt, I have looked into certbot website and I see the following: " Can I use certificates from Certbot for code signing or email encryption? No. Email encryption and code...

Does that command install the addon? The addon is not useful to secure the mail server since i dont have plesk onyx and I've already secured the websites. In the moment when you generate an SSL by gui or without GUI it requires a domain. I guess it is the only domain that will work with the...

Sorry for the late reply. I think i'll install let's encrypt via GUI with "yum install letsencrypt". Haven't updated to onyx because we might change the server and we can't afford anything wrong to happen to it. When creating a letsencrypt SSL it asks for a domain, what is it for?

Good morning. The thing is that I have multiple domains... that solution changes the default SSL by editing " /etc/postfix/postfix_default.pem" but that i guess will work only for one domain. I'm thinking that I need a multi-domain SSL, or am I wrong? Besides, if I use your solution with let's...

ok! So i can set up the dns to "pop3.domain1.pt" and "smtp.domain1.pt" for all of our domains with let's encrypt. Did I get it right? Btw, will "yum install letsencrypt" conflict with the lets encrypt extension on plesk?

Thank you for the reply. I already saw that, but it means that i can only secure one domain, right?

Im not talking about securing websites, but dovecot and postfix. I think i can only use one SSL for each. I guess i need a multi-domain SSL certificate. Let's encrypt only works for one domain, right?

Good day, I was able to secure a mail server with plesk onyx with let's encrypt, but that server only has one domain. The other server i have with plesk 12 have multiple domains, the question is, if I manage to install a SSL from let's encrypt the same SSL will work for all domains? I remember...

I have the following code to add to apache/httpd modsecurity something: " # SPECIFIC: Block #submit #validate #process #pre_render #post_render #element_validate #after_build #value_callback parameters SecRule REQUEST_FILENAME "(index\.php|\/$)"...

I think I found the problem. After messing around the forwarded emails started boucing back with the message: "Diagnostic-Code: x-unix; qmail-inject: fatal: qq trouble creating files in queue (#4.3.0) 4.2.1 Message can not be delivered at this time" The server is supposed to be using...

That is the thing, the emails are not there. I usually use a postfix command to delete queues : "postqueue -p | grep "[email protected]" | awk '{print $1}' | postsuper -d -" . qmail-qstat shows "messages in queue: 374658 messages in queue but not yet preprocessed: 374728" I would like to clean this...

Im using postfix, how come emails are being stored in the /var/qmail/queue/mess/*? I'm sorry, i'm not sure this is a plesk related question, it is using 20gb of disk storage. Is it safe to use this guide: "How to clear qmail queue - General Linux - Admin-Ahead Community" ? Thanks

Thank you sir.

The configuration is 20gb for "/" and 50gb for "/mnt/backup_disk". Hope I made myself clear. Will changing the directory clean "/usr/local/psa/PMM/tmp"? It is full of extension updates. EDIT: Just changed the dir but the tmp files remained there. Can I delete them/move them to the new folder...

Good afternoon, Just received the following email from plesk: Parâmetro de integridade do servidor "Disco > Utilização da partição "/"" alterou o seu estado de "yellow" para "red". (Servers disk integrity > usage of partition "/" change its status from "yellow" to "red") " top - 09:25:48 up...

Good afternoon. I noticed that the server is runing out of space (20gb hdd - vps) and the folder "/usr/local/psa/PMM" / "/usr/local/psa/PMM/tmp" is using 4gb. I know it is related to the backups, but I'm backing up the domains to another hard drive. Is it safe to delete? Can I move the folder...

Is spatkpost a smtp service? Sounds like a misconfiguration. Can you normaly send emails, except by forwarding?

Hi. I'm getting an error when renewing a let's encrypt certificate saying something like "network unreachable : ipv6". I tried disabling the ipv6 but with no avail, so now i'm thinking of properly configuring the ipv6. Will it affect the domain responses by ipv4 in any way? Also, the ipv6...

No. The problem is that i don't know what was done in the server before I got my hands on it.

Hi. Someone is sending emails from our company postfix using non-existing accounts. Luckly the spam filter is filtering some emails and are being sent only to our employes. I have added this in /etc/postfix/main.cf : " smtpd_sender_restrictions = check_sender_access...
