I have a problem with the queue. Mail sent to the queue stops and does not reach the recipient located in the same domain and on the same server as the sender.
For example, a photo from the queue. The mail from the he ****. Pl domain was sent to two recipients. The first one outside the server and the second one to the recipient also in the he **** domain
It is very often the case that many e-mails that are to arrive on the same server stop in the queue.

I think I found a problem. When I uninstall blockcracking then everytthing work without delay.

I think that it is a problem with exim and I put bug reporting to exim group https://bugs.exim.org/show_bug.cgi?id=2346 but now I see that it is a problem with blockcracking.
I have two server with Directadmin and both the same problem.
 
Your sending address, domain, or path might be blocked with blockcracking then. Check the logs from Exim fro more details.

You might want to add trusted senders into a skip list per this guide: https://help.directadmin.com/item.php?id=628
 
Exim logs don't show me anything. After some delay mail is empty from queue.
If I add to trusted senders then I will not have tool to block spammers.
 
Open a ticket with directadmin support, or hire somebody to fix it for you. I don't have anything to add without seeing detailed logs.
 
Exim delays delivery if a server load is too high. Probably that's the case?

Most issues I believe can be investigated and fixed either through logs or in a server console by a man who has enough knowledge and practice. I don't have steps documented for this particular case. In any case I would try a delivery myself and then check logs, server has much more logs to check. I don't have time to guide you on how to read all logs. So the best way would be to contact Directadmin support, they might provide a free support on your server.

If I connect to your server I will charge you an hourly rate.
 
@zEitEr thanks for the suggestions. For me what I try to find time for is to replicate the problem itself. Or to see more discussions like this so that I know I'm not alone experiencing this problem.
What you say about server load can be a reason as I find also other discussions on the internet which tells the same.
The most interesting part of this topic is that the TS is mentioning blockcracking as the problem, disabling this is not something what I tried yet.

Last but not least I had already great support from DirectAdmin for other problems, but you have to come of course with a clear case.
 
I have a problem also when server load is not high. I opened ticket in directadmin support.
 
According to exim.conf (version 4.5) settings:

Code: 
deliver_queue_load_max=10.0
queue_only_load=100.0

no immediate delivery if load is higher than 100.
emails in queue are not processed until LA goes lower than 10.

If you have exim.conf of another version, the values might differ.... So you need to check what you have there.

If it's not the case I don't have any other idea.
 
Hello,

Pretty sure this will solve it:
https://help.directadmin.com/item.php?id=2080

caused by the smtp-time verification not going through.
It seems that exim "solution" is to drop the message to the queue (which I don't fully understand) but tweaking the timeouts (which will cause a longer delay during smtp-time deliveries) will help for some cases.
