Re: new Plugin [sadwl]

shawniverson,

Nicola has created a number of plugins that might be worth bundling (even if disabled by default) with the default v4 EFA.

Re: I have single email domain with multiple backend email server as failover. Is my setup correct?

I don't know how EFA will behave. Easiest thing to do would be to test it. Stop the service on the first mailserver - does EFA error out? Does it try the second in the list? I honestly don't know what it would do. --- That said, if I were setting up a HA back end for my mail service, I'd have two ma...

Re: Problems releasing an infected email from quarantine

Good question!

I confess I was too lazy to debug it when I found the command line work around.

Any takers?

Re: Header information - missing

Sounds like the GeoIP database problem.

Search the forums for recent posts on GeoIP and make sure your GeoIP data files are correct. (sorry, just driving by, no time to search for it myself)

Re: Problems releasing an infected email from quarantine

This is what I do when that happens:
  • edit the /var/lib/clamav/my-whitelist.ign2 file
  • add in the signature MBL_34101911
  • run freshclam or restart clamd
  • resubmit the message
    /usr/sbin/sendmail.postfix -t < /var/spool/MailScanner/quarantine/<YYMMDD>/<MESSAGEID>/message

Re: Avoid mailscanner filename mistakes

Edit the /etc/MailScanner/filename.rules.conf file and commment out that rule using the # character.

I find that rule to be a nuisance.

Re: Getting spam from domains without DNS records

So your configuration seems correct and it should work. The only think I can think of is if it a problem with your DNS? Is postfix able to successfully do the DNS lookups necessary for the checks? Maybe you'll have to run postfix in debug mode to check what happens when one of these connections come...

Re: Change Apache https://hostname/mailscanner

I've not tried this, so these instructions may break your system - be careful. 1/ you could rename the /var/www/html/mailscanner directory to appliance - this would likely break updates as EFA expects to find a "mailscanner" directory - you'll need to edt your conf.php to set the right directory pat...

Re: Disable Outbound Mail possible?

huh? If I understand you correctly, then there is nothing you need to do. Since EFA is not used for outbound, it won't be used for outbound. If EFA is being used as a relay by your internal users, I suggest you find out why your internal users are doing that. If you're really paranoid, you can set y...

Re: make EFA a mailbox server dovecot pop imap smtp

Brave man! You must like administering servers. I used to do "crazy" things like that, but experience has taught me that it is better to go the appliance route so you don't have to worry about things breaking when you upgrade them. Also, with vm's being so easy to use - it's easy for me to spin up a...

Re: Next Major release OS version

Wow. 4 years later on and here we are.

Maybe we should consider Centos 8. After all, Centos 7 is only supported until 2024 which is just around the corner.

Centos 8 will get us to 2027 at least.

Time sure flies!
