OK,
Where to begin?
First background. I've used Plesk going back to version 5. However, in the past, it was always at the Client/Reseller level. I recently move to a VPS using Virtuozzo and Plesk 7.5.3.
1) First thing I did in Plesk was to install Dr. Web (through Plesk). I looked at the log that was generated and no problems were mentioned.
2) After creating my domains, and migrating my sites, I sent out a message through one of my domain's vBulletin 3.0.7 Admin Control Panel. I have about 600 users registered in this forum. I haven't had any mail issues at my last host, but after I sent out a mass mail to all my users (to announce we were back online), I found the following case:
* some users did not receive the email I sent out (I set it so that users who had their 'don't receive admin emails' still got my email)
* a few users got 2 copies
* one user got 200 copies of the email
As you may guess, I am very concerned about that last case.
3) Also in my vBulletin setup, some users who have subscribed to message threads (they get emails when someone posts to the thread) are not getting their notices. Two things about this:
* this problem didn't exist on my last host
* all my vBulletin setttings are the same as they were on my last host
* all my vBulletin settings are correct
Here is a portion of the mail header that a user who recieved two copies sent me:
(I've removed ip/domain name)
Message 1

Message 2

4) In my email client, I'm having a rough time sending out email using my domain accounts (smtp) Seems a tad flaky.
In Server > Server-wide mail preferences
I have the following:
Maximum letter size 20000kB
Relaying authorization is required
pop3 and smtp checked
lock time 20 min
Check the passwords for mailboxes in the dictionary toggles on
MAPS zones has sbl-xbl.spamhaus.org in the field
My mail client has authorization is required checked and the correct login/passwords
Nothing is in my Black List. I have "127.0.0.1 / 32" in my White List per the tip in this thread:
http://forum.ev1servers.net/showthread.php?t=54716
Checking email I get an error that my domain does not support authentication. If memory serves me correct, if I turn off authentication from my mail client, it does send the email, although it tends to take a 'long time' to get delivered. (i.e. I use my ISP's smtp to send my account an email... it arrives but it takes far longer than it should.)
5) In Server > Services management
I am curious as to why, of the running services, SMTP Server (QMail) does not have the stop icon available?
6) I've confirmed that all services/apps are running in Plesk.
7) As per standard procedure, my host set up the following before handing me the VPS (PowerVPS.com)
* Mod_Security
* APF (Advanced Policy Firewall)
* BFD (Brute Force Detection)
* SIM (System Integrity Monitor)
* PRM (Process Resource Monitor)
* LES (Linux Environment Security)
* NSIV (Network Socket Inode Validation)
* SPRI (System Priority)
8) Since I have APF installed,
Modules > Firewall
Has everything set to "Allow incoming from all" with the exception of:
System policy for incoming traffic: Allow all other incoming traffic
System policy for outgoing traffic: Allow all other outgoing traffic
System policy for forwarding of traffic: Deny forwarding of all other traffic
9) At one point, I did ask my host to to check Qmail's qeue, which they did.
10) With Dr. Web on, I recall getting an error in my mail client with an issue with rcthost. My host looked into that had told me they updated the rcthost file. They also switched of Dr. Web with teh explanation that it is causing issues for Plesk users.
11) Whew!, did I miss anything? In a nutshell, I want to be able to use smtp and use my mail client to send mail (using authentication), I want to find out why my forum isn't always sending out mail, and why one user got hit by 200 messages from me. All in all, I would say the problem lies between Qmail and APF. Since I'm a bit of a newbie, I can't think of how to deal with this. I've heard issues about IMAP/Horde on Plesk 7.5.3 from other issues, but in my case, I'm not using either.
