I can send email out to another email account and they will recieve it within 2 minutes, but when I try to receive email from an external account it can take hours or days.

My logs files in the imal\spool directory grows bigger and bigger out of control.  To find out what maybe the possible problem I went to DNS report and receive the following message from them.  WARNING: One or more of your mailservers appears to be an open relay. If so, this means that you are allowing spammers to freely use the mailserver to send out spam! It is possible that your mailserver accepts all E-mail and later bounces it, or accepts the relay attempt and then deletes the E-mail, but this is not common.
WARNING: mail.mbk-inc.org appears to be an open relay: 250 ok its for

I a using Imail 7.07 - please help, with any solutions.  Thanks!

Well, you clearly changed something on mail.mbk-inc.org without reposting, since it's no longer an open relay.

However, in the meantime, you were listed on a few blacklists--see http://www.dnsstuff.com/tools/ip4r.ch?ip=24.153.154.62.  You should set to getting yourself removed from these as soon as possible.

It is possible that both your local delivery delays were caused by the abuse of your mailserver by spammers during the time that you were open and related resource quenching; however, local delivery is not _directly_ affected or blocked by blacklisting.

In any case, if you do not provide log snippets, it's not possible to divine the exact cause of delays in either direction.

There's more than one blacklist; all are listed at that URL.  Delisting procedures are different for each blacklist and should be documented at their home URLs (and some are all but impossible to get off).  You'll have to give a shot to each and report back if there are specific problems.

Thanks Sandy,

I think that the problem was that I was getting Spam, because I had my setting in Imail set to relay mail for anyone.  Now I have it set to relay for local users.  Should I keep it like this or should I make it so that relay mail for 192.168.0.0 range which what my users have since we are using NAT? 

Also it now takes a long time or users cannot get email from the outside world email account.  We are using outlook.  Is something wrong with my pop3 or Imap settings?

Attached is my long file, the file has gone down from 8 meg to under 1 meg.  Thanks for any help, I am new to email admin.

my advice,

use either "no mail relay" or "relay for ip"

the other settings are insecure

it's ok now with your log, you should be afraid of rdeliver entries only

As Dmitri said, you MUST use 'Relay for Addresses' or 'Do Not Relay' (both of which, despite the implications of the second option, allow you to use SMTP AUTH as well).  Anything else leaves you with an open relay.
