Re: Emails that are retained for containing .dat files

Sorry for the delay in getting back to you.

The messages you sent me passed into my system without any trouble at all and I cannot yet figure out why you can't get the messages but I can.

Re: User has a potentially spammy TLD in their email

You need to provide the spamassassin headers so we can work out why this message is being marked as spam.

Re: transport to multiple exchange server (DAG)

If the document says 1 domain per line, then that's that.

Until the configuration UI is changed to support multiple IPs per domain in the transport file, you'll have to maintain it by hand.

Re: transport to multiple exchange server (DAG)

Just a wild guess, but would this work in your transport file instead?

Code: Select all

comet.it smtp:[10.1.1.126]
comet.it smtp:[10.1.1.151]
The proper solution is to allow the efa configuration to support multiple destinations correctly. That should be an enhancement request for Shawn.

Re: Corrupt Bayes Table

Sorry for the delay.

Can you tell me what your host OS is, what database you are using and what version of EFA you are running?

I'll need to find the correct SQL creation command from the installer as I don't want to guess and give you the wrong command.

Re: Corrupt Bayes Table

Do you have a backup?

If not, then you will need to recreate the related tables, make sure they are in innodb format and then repopulate the tables by retraining your bayes filter with known spam.

Good luck!

Re: Whitelisted IP still rejected

Good to hear you found a solution. Another way to have handled it would have been to add a .biz handling rule to the spamassassin local.cf to give .biz domains a bump up in spam score. That way if a message really did come through that was legitimate, you could train the system to recognize it while...

Maybe I didn't state it correctly as my knowledge is not perfect. Ports 25, 465 and 587 are all use for SMTP transmission which may or may not be encrypted. The rest is just details. Modern mail servers prefer encrypted connections. Old mail servers are happy to use unencrypted. Many ISPs block port...

Thats answering me, that you open port 587 to the outside and somebody brute force trying to make your EFA Box as SMTP Relay and your secure log is generating error report. Or you open port 587 cause you use authentication level on your mailserver to communicate to your EFA Box for outbound. [snip]...

postfix doesn't do sasl authentication.
