Topic: I can send but not receive email

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): v1.1
- Deployed with iRedMail Easy or the downloadable installer? Downloadable installer
- Linux/BSD distribution name and version: Ubuntu Server 18.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MariaDB
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

I installed iRedMail on a new server, I migrated the data from my old server, everything was successful, there were no errors. The problem is that after resetting the information in the new server, I can send mails, they are stored correctly in the server and they arrive to the recipient but I cannot receive mails.

If I send an email to the server with iRedMail it never arrives.
I have already verified that the directories have the corresponding permissions.
The A and MX records are correct. In fact, I only had to update the IP of record A to point to the new server.



Execute the following commands:
sudo chown -R vmail:vmail /var/vmail
sudo chmod -R 755 /var/vmail
sudo chmod -R g+w /var/vmail
sudo find /var/vmail -type f -exec chmod 664 {};
sudo find /var/vmail -type d -exec chmod 775



This is the result of running the following command
sudo lsof -i -P -n | grep LISTEN

I ran out of ideas, I've been consulting publications with the same problem but I still can't find a solution, could someone help me?

The ports are also open within the network, I've exhausted most of the possible causes of this problem but I can't think of what else it could be.

I've sent mail to myself from iCloud and Gmail, neither of which has returned any error messages saying that the server or mail address can't be found, so I've assumed that they arrive at the new server but aren't stored by some erroneous permission or something else.

Re: I can send but not receive email

I would say, just wait.
Sending mail is something other than receiving, i guess the DNS a record is not propagated worldwide yet.
Give it at least one day before you start troubleshooing

I did the migration 2 days ago and only today I realized that the emails are not received.

Re: I can send but not receive email

Is there anything in in the logs that indicates anything incoming?

Check in /var/log/mail.log to see if the messages were received, and if they are then check in /var/log/dovecot/lda.log to confirm it was transferred to the correct folders

Re: I can send but not receive email

Does your ISP block port 25?

Re: I can send but not receive email

Post 25 is not blocked by my ISP.

The worst solution I could think of was:

Create a virtual machine
Install iRedMail on it
Backup the information and restore the data on the local server.
Once I made sure my local server was running successfully after restoring the information, I reinstalled the OS on my production server to perform the iRedMail installation from scratch.

Now instead of restoring to the production server, I manually re-added all the domains and created the email accounts.

I changed the passwords on the local server to be able to access the emails of each account, to avoid confusion I opened each account individually, example:
hi@domain.com
Using Thunderbird I connected to the production server and the local server with the same email account. I only had to change the host so that the email client could find the account on each server. I moved the emails from the local server to the production server.

I moved the incoming and outgoing messages that are the most important.

It's too stressful because there are too many steps that I'm skipping, it took about 1 day but possibly it would have taken longer to find the solution and I couldn't waste so much time doing it because the server must always be up and running or at least most of the time.

After I moved all the information manually and account by account, I restore the information from the vmail database on the local server, the reason is so I can copy the encrypted password manually and update it on the production server so I don't have to give users a new password or do anything else.

I don't know if it was a good or bad decision, but under the stress I decided to do it, if someone in the future has this problem, this solution is stressful, tired, requires too much time, you need patience.

You also require some advanced knowledge, otherwise it will be more confusing and difficult for you to do so.

Everything's working fine now.
