Default Multiserver setup - Mail server installation

I edited this post a few times, but would like a couple of eyes on it to make sure everything I did to fix it was the correct way to fix the problems and won't create any future issues when it comes upgrade time. The next posts I make will be about having trouble setting up TLS and also some outgoing issues I'm having. Outgoing works with webmail (I'm using roundcube) but not through email clients, but I hvaen't gathered enough information about this issues yet to make a post on it.

Ubuntu 12.04

Followed instructions from the ISPConfig manual for mulitserver setup. Some of the steps appear to be slightly outdated in the manual, but nothing major as far as I can tell, the biggest thing being the volatile repositories I think.

Have my ISPConfig interface working well on the first server, and the install on the mailserver, mailserver is giving a bunch of various errors that I'm having trouble sorting out. I've searched a bit, but cannot find exact answers for what I'm running into

I fixed a few of the problems myself, but I'm going to discuss those just to make sure I fixed them the correct way:

firstly was the error "mailserver dovecot: auth: Fatal: Unknown database driver 'mysql'"

I fixed this by installing the package "dovecot-mysql" I dont' know if this step is missing in the tutorial, or I missed it, or there is some other problem.

Secondly, the error " fatal: pipe_command: execvp /usr/bin/maildrop: No such file or directory" the email gets to the server, but won't deliver to the mailbox

I installed the maildrop package, not sure if I should have the relay setup differently or what I'm doing wrong here.

Thirdly, I commented out the line "# -o smtpd_bind_address=" in postfix master.cf because of a warning at startup, not sure if that is a problem or not.

postfix main.cf:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name.  The Debian default
# is /etc/mailname.

biff = no

Found a problem in my postfix main.cf that was creating the delievery problem, got that fixed, the "Virtual transport" was set to 'maildrop' it is now 'dovecot'

okay, so, the outgoing situation.

Through webmail I can send and reply to emails without any problems, setting up an email client, in this case, thunderbird, I get the followign error message:

An error occurred while sending mail. The mail server responded: 5.1.0 <sending@emailaddress>: Sender address rejected: User unknown in virtual mailbox table. Please check the message recipient receiving@emailaddress and try again.

It's almost like it's trying local delivery to the receiving email address, although I cannot be sure (the receiving address is definitely NOT local)

Edit: not a local delivery issue, doesn't work for local delivery either, must be an auth problem?

Switched to windows mail, same type of issue, but turning on smtp auth fixed it, however still hangs with thunderbird no matter what settings...

Mail accounts are virtual, i.e. they don't have an actual account on the machine. Thus your account name should be accountName@domain.com and the mail server name should be domain.com. So you would be actually logging into accountName@domain.com@domain.com in thunderbird. If after making the modification above you still see no auth attempts in the logs, try ensuring that you are connecting on port 25 in thunderbird's outgoing mail server settings.
