Hi,

I was told how Postfix is better than Exim, is this the case and is it fully supported by DA as I was told it was an option during install, but I don't remember seeing it, if so I wasn't aware it was.

Also, would be it worth changing over as i'm looking to redo a server and backing things up, would it simply just work when restoring the account backups with the previous Exim mail setup or would this require changes?.

My reason for this as each time I keep having exploit issues and each time I find more ways to secure the server upon setup, however it's always the same issues that happen, they manage to obtain email access and send emails from email accounts, break server logging and other things end up with often higher loads than normal on system resources, I've tried many ways to try resolve this and find the cause, however never to any avail as all places to check are checked, various tools ran and zero results.

Hope for some helpful answers.

Regards,

V4mpire

Don't know but you can use external mailservers and use such setup in DA.

This could be handy to test if it is only mail that is the poblem for your da box,

Also look here don'r know that part for remote mailserver support in DA

[Request] Remote Email Server

But better first to start looking for the real cause how they get the email account access!

And this could be helpfull maybe to understand some of exim parts

Restrict sender email address to authenticated linux user

Most email clients have the ability to create multiple identities or send from addresses. On my Postfix/Dovecot server, I was able to configure a setting so that any emails with a from address (envelope address?) that is not associated (by means of an appropriate virtual account mapping) to...

That's what I thought as I don't remember seeing it each time i've installed a directadmin server.

other processes at times end up with excessively high loads, but doesn't help find the problem, as for the last one, I might have misunderstood at quick glance, but seems to imply checking a valid address being used for the emails, I'm getting the notifications within DA message Service telling me the accounts sending emails, which is how I first seen this was happening, so they are valid accounts even the main accounts say "user1" where the main DA user account is the login for the email, then additional email addresses will show as user@domain.

The problem though is i've done all checks I can find to see hwo they're getting in to do it as it's the same each time, system logging breaks, excessive emails sent, some processes at times have high loads, but usually low, i've tried searching for something that could be doing it like a script, i think the one's that spike is apache and mysql, so it could be like a spam script running on the webserver sending them, but it's not in the user account locations and i don't see anything in the apache configs showing any additional locations of vhosts etc.

If I backup and reinstall the problem goes away and many months, so that would say it wasn't something in the user accounts else i'd expect it to start again straight away, I could be missing something simple when trying to find the root cause, if I was able to do this, I could then try to work towards a solution to stop it from happening as it's always the same way.

I had seen this, not sure where the person got their information, thought would ask to see if something had changed since I last installed directadmin

What do you mean by this? Are you getting spam, blacklisted, viruses? Are you on the latest versions of everything?

after so long with each install, multiple email accounts are used to send out a lot of emails hitting the email limit on the accounts, even the main email addresses linked to the main user account, which has caused my ip's to be blacklisted more than once, I always do updates when available
