So this question is again on the table. I have tried to get my answer from forums documents but I wasn't able to find the desired answer.

So, Here is my question I have created a mail server with postfix now what I want is to create quotas for a particular user to send only located number of mail I mentioned. So, for example, if I had 3 users

User1@domain.com 30mails

user2@domain.com 60mails

user3@domain. ...

I thought this was a quite common situation, but I'm struggling a bit getting this to work in the easiest way possible, and also, I'm not sure if I'm doing it in a good/recommended way by now.

I have two servers that can communicate via a LAN (and also, both have public internet IP addresses). One runs Postfix, the other one serves some websites.

What I want to do is to be able to send some mail (e. ...

I have a task to implement sending messages by authorized users through some of their IP addresses. In other words:

         +-------------+
user1 -> |outgoing IP 1|
user2 -> |outgoing IP 2| -> 
user3 -> |outgoing IP 3|
         +-------------+

(one user - one IP)

In this scheme, incoming IP of a mail server can be the same for all users, only outgoing IP matters.

Now I am running a se ...

Using Apache/mailcow I’m setting up a home email server. I followed the mailcow dockerized tutorial. And was able to connect to my mailcow site at:

http://mail.example.com:8080

I had to use 8080, because I have my website also setup on this server.

first question here, take me slow.

I have installed dovecot, postfix and Roundcube webmail in a VM to test a new mail server for the company I work for. All good until I try changing a password as a logged in user from roundcube settings->password.

What I have done:

• Enabled password plugin in roundcube
• Set the driver to "chpasswd" as my users are system users created with "useradd -m user passw ...

I've configured SSMTP to send system messages for users with a UID < 1000 in /etc/ssmtp/ssmtp.conf:

root=to@mydomain.com
rewriteDomain=mydomain.com

If I send an email to root (echo test | sendmail -v root) for example it gets properly delivered to to@mydomain.com (as per root in /etc/ssmtp/ssmtp.conf).

However this doesn't work for user accounts with UIDs greater than 1000. If I send an email  ...

I'm a bit stuck here at the moment and will appreciate every push towards the right direction to solve this issue.

My two goals are to get an OpenVPN server running on a remote VM (Digital Ocean Droplet) and also run my postfix server on that VM. The OpenVPN connection is routing my DNS queries to a Pihole which provides me with proper ad blocking when I am not at home (where there is a pihole on ...

A simple question, is it enough to open port 25 to internet for running a mail server that only send and recieves email, and don't have any external "clients" (imap,pop3)?

(all clients are internal)

Our postfix logs are being filled with messages that appear to be stuck in the mail queue.

I believe this may have been caused by a recent DNS outage. The offending mail was originally intended for node@hostname but postfix was unable to resolve its own domain.

However, what I don't understand is why the messages have been prefixed with owner-owner-owner-owner-owner-. This is repeated hundreds of times  ...

I have a Domain A.Com Which is using Zoho for my emails Now I want to have B.A.Com (B is subdomain, so emails will be Test@B.A.Com)

I dont know how to setup DNS for my subdomain.

What I did so far....

I created a new DNS ZONE for Domain B.A.Com for my A.Com I added a new NS record for B and point it to B

I am still unable to ping B.A.com (Request could not find Host). what am I missing here?

I have a web app running on a shared server account for the domain example.com. The web app needs to send the occasional email to the app adminstrator.

The domain example.com is using Outlook.com as the email server.

How can I either:

a) Configure the web app to send emails via an Outlook.com mail account (can you point me to the instructions/settings to configure this?), or

b) Configure the included mail ...

Some cloud business offers "always-free" VM instances. Not quite big, but enough for me, so I’m going to migrate my infrastructure there, including mail.example.com. That machine handles incoming mail for @example.com (example.com MX 10 mail.example.com). However to also send email from @example.com the machine needs a PTR record (192.0.2.1 PTR mail.example.com). The cloud provider, however, doesn' ...

The challenge am having is only google workspace emails can send/receive emails but webmails emails can only send mails but not able to receive emails.

I have a Postfix email account abc@mydomain.com and the following two aliases:

mydomain.com     -> xyz@mydomain.com   # catchall alias
abc@mydomain.com -> abc@mydomain.com

Now the second one looks silly but if I remove it, every email which is sent to abc@mydomain.com gets delivered to xyz@mydomain.com even though (1) abc@mydomain.com is an account, (2) is enabled and (3) is not a send only ac ...

I have a Postfix (v2.10.1) mail server running on Oracle Linux 7.9 that forwards mail for LDAP user accounts via the ~/.forward files located in NFS mounted /home/ directories.

The system works as intended for all of the NFS accounts, but I have one account created locally with a home director ...

Problem

I have successfully set up a Postfix mailserver with an SMTP interface, set up DKIM, DMARC, SPF, all that stuff.

But I had a problem when testing the delivery of emails to Gmail.

Namely, SPF would pass if I sent it by the sendmail command from the server (some of the ARC-Authentication-Results header content of the delivered message in Gmail):

spf=pass (google.com: domain of redacted@example ...

I am trying to link up a dummy email address to two different email addresses:
contact@example.com -> user1@example.com and user2@example.com
This would mean that mail sent to contact@example.com would also get BCC'd or forwarded to user1@example.com and user2@example.com

I have an app for which e-mails sent to a specific address, x@example.com, should be received by SES for analysis of e-mail attachment and storage. However, I would like to handle the other E-mail addresses, y@example.com, z@example.com, associated with the domain outside of SES.

To receive the e-mail sent to x@example.com, I need to change the MX record for example.com. As I understand it, this  ...

I recently purchased a domain and I am planning to use the subdomain smtp.example.com for my mail server and mail.example.com to host my webmail app. Could there be any issues with using mail for something other than a mail server?

I have a problem with my postfix servers. When I send an email to an non-existing domain or mail address I get a bounce mail (which is normal) without From address nor Subject. I tried to create my custom template for bounced mail as the documentation shows but I had no luck. I still receive the mail like that.

This is my bounced mail:

This is a MIME-encapsulated message.

I am new to the world of Web Email and domain hosting. I was looking into projects like https://temp-mail.org/en/ and https://kopeechka.store. In these applications I can receive an email address, receive emails to those email addresses, and then delete the email from a simple python client using API calls to their API's. I want to replicate something similar using my own domain name(I have not regist ...

I want to send a mail from a website. The mail server from this domain is not publicly reachable, so I can't use that to send the mail.

The webserver that hosts the website has another email server that I can/have to use. But I want the FROM to be the website domain.

How can I set this up without my mails being marked as spam for claiming to be from the website domain when the mail server that sent  ...

we're a small company with about 25 mail addresses. Since our current mail provider (aruba) is not reliable enough, we wanted to migrate to a more professional mail system.

Q - If I was using a second domain in my workspace for email outreach, and set it as an alias domain to avoid lots of extra seat costs (duplicates users to new domain and then users can use one inbox/login).

Can this effect my main domains reputation in any way?
