Couple things..I appear to be top posting. What is the preferred
conversation rule. I use Thunderbird. Way back in the day, I seem to
recall a setting
which played to the bottom posting preference.
On the conversation here. I've set a reverse proxy on my gateway apache
server pointing to the backend apache server, which is running
mail services. (It doesn't have to be that way, I'm just trying to keep
server counts down.)
On the backend apache server here is an example of my Virthost. However
I think the following line should be "localhost"
current -> ServerName postfixadmin.domain.com
replace with something like ->
*ProxyPass* /sample http://localhost:8080/sample *ProxyPassReverse*
/sample http://localhost:8080/sample
<VirtualHost *:80>
ServerName postfixadmin.domain.com
DocumentRoot /var/www/postfixadmin/public/
ErrorLog /var/log/httpd/postfixadmin_error.log
CustomLog /var/log/httpd/postfixadmin_access.log combined
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
<Directory /var/www/postfixadmin/public/>
Options FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
I just don't think I get this yet, but very close. I have three reverse
proxy conf that are working for websites.
But this one simply says "File not found". The logs say
error_log
[Tue Sep 23 23:24:19.181827 2025] [proxy_fcgi:error] [pid 46973:tid

Thanks for any help

Ok. Is there a recommended place for the TLS, or either one is
fine. Just confiming.
Sounds like I'll need to remove a cert on one of the servers
thinking..Yes/No
Thanks Frank.

Hi there,
I'm setting up and email server which is reverse proxyied
behind a front
end apache server.
For the same domain...my dns has both a primary web server
server, and
an email server sitting behind a single wan ip.
First question.
Is this possible?
At this point all email is working except smtp, which I'm
thinking is a
certificate problem.
So I have certicates on the email server apache and the
apache server
providing the reverse proxy.
And of course Postfix and Dovecot could have config issues,
but mostly
here I'm looking for verifying my described concept is
achievable using apache.
Comments or links to feasability and tips are always appreciated.
Thanks,
Bret

Email and HTTP server had nothing to do with each other,
practically. A reverse HTTP proxy can be used to host a webmail
interface to handle those emails, sure, but then just handle the
TLS termination either on the edge, or the inner server.
For the latter, just use SSLProxyEngine on.
It depends on what the backend interface requires - if it redirects to
https:// automatically, then you'll need to offload TLS to the proxied
server with SSLProxyEngine on.
Otherwise, you can handle the TLS handshake on the edge server and
speak non-TLS to the inner servers.
