yapadu,

You are correct. SpamFilter will never send emails out directly to the internet. All emails are always delivered to your destination SMTP server for final delivery, so if using SpamFilter for outgoing emails, care must be taken to avoid mail loops.

Perhaps Roberto can confirm, even if meatboy routes outbound email to spamfilter, spamfilter will still turn around and send the message back out through the defined smtp server right?

I think you would actually end up with a loop, exchange sends to spamfilter and spamfilter will return it to the exchange server (if that is defined as the outbound smtp server in spamfilter). 

Is there any condition that would allow spamfilter to deliver directly to internet hosts? ie. hotmail.com?

Thank you for that solution Roberto, I have edited the file with addresses to suit. I had done as yapadu's had suggested to keep email moving but it may be handy to have SF to be able to send if some issue occurs.

One reason I can think to use SF for outgoing email is IF you have the antivirus addon (we don't) it could scan outgoing emails for viruses making sure your email is clean.  This could help if you have an infected PC on a network!

So far I have found SF for ISP to be very effective. Big smile

Tim

Tim,

You can exclude IPs from being blocked by the greylist filter using this setting in the SpamFilter.ini file:

;Add any IPs (separated by commas - no wildcards) that you do not wish to be automatically added to the Honeypot IP blacklist. This setting also prevents those IPs to be added to the IP cache blacklist
DoNotAddIPToHoneypot=

Tim,

What you are trying to do is not something spamfilter is designed for I don't think.  It will never relay email to the Internet, you should let your exchange server be responsible for outgoing email.

Even if you had your users send their email direct to the spamfilter server as the outbound server it would still want to forward the messages to your exchange server for final delivery.

No advantage to having your outbound to through spamfilter, and not something it is designed for either.

Apologies is this has been discussed before but..

we are running current release version of SF and experiencing a 99.8% hit rate - its working very well. We have done a lot of tweaking and its paid off. Clap

I was considering sending email from our exchange mail server to SF for final delivery but found it greylists our internal server immediately. I put our internal subnet into the excluded Domain/IP whitelist but this did not allow the internal server/s to send straight through. Cry

Is there any advantage for me to use SF for outgoing and how can I get all my internal SMTP servers to be ignored by the greylist function? Confused

Many thanks

Tim
