+# Steps:
+Note:
+- "$maildomain" = mail.example.org
+- "$domain" = example.org
+- "$subdom" = mail
+
+# Run `emailwiz.sh`
+
+Set it up normally for your first domain, check that it works fine.
+Then continue with the next step
+
+# Generate new certificate
+
+Not totally necessary for mail to "just work" but it will help, in this case I specified --standalone but do use --nginx or --apache instead, if your email service depends on one of those, if not sure, leave it as standalone.
+This is the line from the script:
+
+```sh
+certbot -d "$maildomain" certonly --standalone --register-unsafely-without-email --agree-tos
+```
+
+Note: Redirect at least your mail subdomain from your OTHER domain(s). Later on you'll have to also add other records for emails to work! See DNS Records step.
+
+# Dovecot
+Dovecot is easier, you should be good by just adding these lines to `/etc/dovecot/dovecot.conf`
+Note: Remember to actually generate the keys with certbot, like in the "Generate new certificate" step below.
+Note: Uses TLS SNI, according to [Dovecot's docs](https://doc.dovecot.org/configuration_manual/dovecot_ssl_configuration/), it is tested in clients:
+- Thunderbird (Linux)
+- K-9 on Android (merged Sept 2015 - https://github.com/k9mail/k-9/pull/718)
+- Apple Mail (according to https://forums.cpanel.net/threads/mail-ssl-sni.454592/ )
+- Mutt (ticket https://dev.mutt.org/trac/ticket/3923)
+- NeoMutt (since 2016-03-07 according to https://www.neomutt.org/feature/tls-sni )
+
+```
+# mail.domain.org
+local_name mail.domain.org {
+    ssl_cert = </etc/letsencrypt/live/mail.domain.org/fullchain.pem
+    ssl_key = </etc/letsencrypt/live/mail.domain.org/privkey.pem
+}
+
+# mail.otherdomain.org
+local_name mail.otherdomain.org {
+    ssl_cert = </etc/letsencrypt/live/mail.otherdomain.org/fullchain.pem
+    ssl_key = </etc/letsencrypt/live/mail.otherdomain.org/privkey.pem
+}
+```
+
+# Create vmail map for the certificates
+Add these entries in the vmail map to specify the certificate for each domain you need. You have to add them also for your already configred domain.
+This file is in `/etc/postfix/vmail_ssl.map`
+```
+mail.domain.org /etc/letsencrypt/live/mail.domain.org/privkey.pem /etc/letsencrypt/live/mail.domain.org/fullchain.pem
+mail.otherdomain.org /etc/letsencrypt/live/mail.otherdomain.org/privkey.pem /etc/letsencrypt/live/mail.otherdomain.org/fullchain.pem
+
+```
+
+# Generate a new DKIM key
+Technically this is not necessary either since you can use the same key as your main domain, generated by emailwiz. However, some email clients and/or recipients might complain.
+Note: These lines are totally ripped off from the emailwiz script, I didn't come up with this I just found it useful to share the steps to reproduce my setup for multiple domains.
+Note: Obviously use your second domain name, first one is already generated.
+
+```sh
+mkdir -p "/etc/postfix/dkim/$domain"
+opendkim-genkey -D "/etc/postfix/dkim/$domain" -d "$domain" -s "$subdom"
+chgrp -R opendkim /etc/postfix/dkim/*
+chmod -R g+r /etc/postfix/dkim/*
+```
+
+# Add DKIM key to keytable
+This file is in `/etc/postfix/dkim/keytable`
+The first one should already be filled out.
+```
+    mail._domainkey.domain.org domain.org:mail:/etc/postfix/dkim/domain.org/mail.private
+ +  mail._domainkey.otherdomain.org otherdomain.org:mail:/etc/postfix/dkim/otherdomain.org/mail.private
+```
+
+# Add entry in signing table
+This file is in `/etc/postfix/dkim/signingtable`
+Again, first one should already be there.
+```
+    *@domain.org mail._domainkey.domain.org
+ +  *@otherdomain.org mail._domainkey.otherdomain.org
+```
+
+Make sure both signing and keytable paths are present in `/etc/opendkim.conf`, like this:
+```
+KeyTable file:/etc/postfix/dkim/keytable
+SigningTable refile:/etc/postfix/dkim/signingtable
+```
+
+# Virtual alias
+Add your desired email address, followed by the user the mail should be sent to.
+As stated before, you will need to do this for existing and new users.
+This file is in `/etc/postfix/virtual`
+```
+exampleuser@domain.org exampleuser
+eggsample@domain.org eggsample
+otheruser@otherdomain.org otheruser
+yetanother@otherdomain.org yetanother
+```
+
+# Tell postfix about it
+Add these lines at the end of your postfix configuration.
+This file is in `/etc/postfix/main.cf`
+```
+virtual_alias_domains = otherdomain.org
+virtual_alias_maps = hash:/etc/postfix/virtual
+
+# provide the map to be used when SNI support is enabled
+tls_server_sni_maps = hash:/etc/postfix/vmail_ssl.map
+```
+
+# Apply and restart
+
+Run these to apply the new configs and
+restart the services.
+
+Note (edit): I had some issues when NOT using the `-F` option
+in `postmap -F /etc/postfix/vmail_ssl.map`, it references files, so make sure to use it.
+
+```sh
+postmap /etc/postfix/virtual
+postmap -F /etc/postfix/vmail_ssl.map
+systemctl restart postfix
+systemctl restart dovecot
+systemctl restart opendkim
+```
+# DNS Records
+In your second domain's panel, point the mail subdomain to the VPS, as usual, then add the same DNS records in `dns_emailwizard`, but do swap the domain name, for example:
+```
+domain.org        TXT     v=spf1 mx a:mail.domain.org -all
+```
+Would be
+```
+otherdomain.org        TXT     v=spf1 mx a:mail.otherdomain.org -all
+```
+
+Also, the output of the following commands is the TXT record for the new DKIM key (generated in the "Generate a new DKIM key" step).
+```
+pval="$(tr -d '\n' <"/etc/postfix/dkim/$domain/$subdom.txt" | sed "s/k=rsa.* \"p=/k=rsa; p=/;s/\"\s*\"//;s/\"\s*).*//" | grep -o 'p=.*')"
+echo "$subdom._domainkey.$domain   TXT     v=DKIM1; k=rsa; $pval"
+```
+
+# For new accounts
+
+- Add unix user as explained in the main emailwiz documentation.
+- Add new entry in /etc/postfix/virtual
+- `postmap /etc/postfix/virtual`
+- `systemctl restart postfix`
+
+# References:
+[Dovecot SSL configuration - TLS SNI Support](https://doc.dovecot.org/configuration_manual/dovecot_ssl_configuration/)

+
+# Notes & edits
+
+Note: I had an issue with thunderbird where it could not verify server configuration. Checking `systemctl status dovecot`, it was a login issue even though I'm not trying to log in. I just clicked "done" when adding new email account without checking for server configuration and it works just fine.
+
+Note (edit 2023-07-20): I noticed when using **Thunderbird**, for whatever reason it grabs OTHER domain names if you have multiple subdomains, for example, Thunderbird would get turn.example.org's cert instead of the appropriate mail.example.org. I noticed this because I was getting flagged mail when sending to corporate or institutions mail, BUT when using claws-mail (based, lightweight, simple client), it would actually get the mail.example.org cert. I don't know how to fix this since I'm not a Thunderbird user and I couldn't find any obvious way to do it. But note that it might happen :)
+
+Note: (edit 2023-07-21): Gmail will complain about PTR records:
+"_Gmail does not accept messages from IPs with missing PTR records._"
+This is expected since you have (ideally) only one reverse DNS record for IPv4 (A) and IPv6 (AAAA), which is probably for your main domain. According to what I looked up online you COULD have multiple reverse DNS addresses but people say it might be worse than having one or even none. I don't exactly know the implications of this approach because I'm no expert, but receiving mail should work just fine.
