Roundcube doesnt send emails

Hello,
I followed several times this perfect server article and I still am unable to send emails. My setup:
Test Ubuntu server hosted on my machine using Vmware. The domain I'm trying to use is domain.com and I have entries to hosts file that points it to this server. After finishing the guide everything works fine, apart from being able to send emails within the same domain, example from [email protected] to [email protected] - both mailboxes created and passwords are correct.

mailq gives the following:

Code:

                                         [email protected]

I tried removing AV, also increased the memory size of the machine, no luck.

 

Post ISPConfig questions on ISPConfig forum.
Then start with this: https://www.howtoforge.com/community/threads/please-read-before-posting.58408/
My signature has link to e-mail setup with ISPConfig Tutorial.
What does mail log say about the attempt to send that e-mail?

Is that the only thing that is not working? So you can send to everywhere else?

 

Hello, thank you for the reply and apologies for posting in the wrong section. To clarify, this is an isolated system I am building for a subject at school. It is hosted in my machine, it does have outgoing internet connection but I dont intent it to make public anywhere, is only for education purposes. After following the instruction I am unable to send any emails anywhere. So sending of emails is not working. I tested this with the following:
Test 1: On ISPConfig I created a new site: domain.com and I created two email accounts [email protected] and [email protected]. Trying to send emails between this two accounts fails with the error I shared above.
Test 2: On ISPConfig I created two new site: domain.com and domain2.com. I created two email accounts [email protected] and [email protected]. Trying to send emails between this two accounts fails with the error I shared above.

Per your request, below the notes of mail:

Thanks for your reply. The issue looks similar. I tried the solution provided on the other threat but it didnt solve my problem.

 

Thanks for the reply. Apologies if I expressed myself wrongly. I have been using ISPConfig for about 4 years so I am very familiar with the basics. Indeed, thats how I setup the email, by creating the email domains. The issue is not related to that, obviously.

 

Hello, I followed the perfect server guide rigorously at least 5 times, with the same issue all the time for the past 2 days. I havent made any other changes.
Attached master.cf

 

You comment on the other post was:

I went to ISPConfig - System - and changed Content Filter to rspamd and back to amavis, but it didnt fix anything.

Please, I am in urgent need to get this fixed. If you think the guide I followed has some errors, can you post the correct solution? I am still very confused what has to be done, and everyone on this threat is talking about something different.

 

Oh man, you just made my day!!!!
Finally it's working. "ispconfig_update.sh --force " and now I am able to send and receive emails. Thumbs up!
