Hey all...

In my third day of evaluating Spam Filter, and mostly lovin' it.  Had a glitch today, however, and was wondering if this had happened to anyone else.

My setup: running Spam Filter on IP xxx.xxx.xxx.2 (DNS A record "mail2") and Imail 8.15 on IP xxx.xxx.xxx 1 (DNS A record "mail").  Both are running on port 25.

My monitor told me this morning that "mail" was not responding.  No new mail was coming in, and users could not send mail.  In looking into it, it appeared that Imail's SMTP service was running just fine, but wasn't accepting any connections.  The Spam Filter logs showed that it was receiving mail, dealing with the bad stuff, and then attempting to forward the good stuff to Imail's SMTP but receiving a "not available" message, so it was queued for later delivery.

After a few hours of mucking around with it, I finally ran FPort and it told me that the only program running on port 25 was SpamFilterSvc.  Even though Imail told me that it was running on port 25, it apparently was not.

What I *think* solved it was to stop both services, start Imail SMTP, and then start SpamFilterSvc.  After I did that, both services showed up in FPort, and everything seemed to fix itself.

My guess is that Imail's SMTP service stopped for some reason (it happens occasionally) and when it attempted to restart it found that since Spam Filter was already running on port 25, it saw a conflict and did not bind to the port.

As I understand it, there should not be a problem running both SpamFilter and Imail on the same port as long as they are on different IP addresses.  Do I have that correct?  Is there an issue with the order in which the services start... i.e. does Imail need to be running before Spam Filter starts?  Or am I way off base here?

(Something else I thought of... do I need to "delete" the IP address used for Spam Filter from Imail?  It appears that I can do that)

Also, make sure you configure SpamFilter as well to listen only on xxx.xxx.xxx.2. You can do this on the "Settings - Configuration" tab, under the "SMTP Listener Socket". That way, even if the xxx.xxx.xxx.1 IP becomes available when Imail stops, SpamFilter won't try to bind to it.

As a side note, SpamFilter will only bind to IPs upon startup. Once it's running (and configured to bind to all IPs) it won't use an IP even if it frees up.

Mmm... what version of Imail are you running?  According to the Imail KB article I am looking at, it appears as though that option only exists in +v8.2, and I am running v8.15.

Another option I am looking at is to make the SpamFilterSvc dependent on the Imail SMTP svc, so that if Imail restarts, it will force SpamFilter to restart also.  If all else fails...

I am running Imail 8.22.  I wasn't aware that older versions did not support the single IP.  Good luck - They'll want an arm and a leg for an upgrade.

mstsc -console

type that into the run box and you get the console of rdp, which then you will have the gui when using terminal services.
