Issue is still persisting and I am still no longer closer to solving this puzzle than I was 9 hours ago. Being bombarded by Exchange server from blank sender to my PVEMailgateway. Each entry above has the following log: Mar 23 18:13:44 mailgate postfix/smtpd[11168]: connect from...

Yeah 192.168.1.80 is the sanitized IPv4 of my Exchange 2013 Server. Today all of a sudden the CPU has just spiked and remained there Don't have much in my queue though which is weird. I'm doing a reboot now and I'm trying to figure out Exchange 2013 logs... geez Microsoft logs are garbage...

I take that back, I still have no idea wtf is happening. My Mailgate is over 100% CPU utilization and consuming all its RAM as well. My exchange server is dumping all this to my mailgateway and I dont know why or what or how. Mar 23 15:24:50 mailgate postfix/smtpd[24823]: connect from...

So I looked into the nature of the error more and run into this Postfix documentation: https://www.postfix.org/SMTPD_PROXY_README.html Seems the error and the mysterious "supplier@mail.domain.tld" had to do with Before Queue Filtering. I recalled that I had also enabled that setting as of...

I am extremely perplexed by these error notifications I am receiving from my Mailgateway. This email address (supplier@mail.domain.tld), which does not exist, is involved somehow and I am confused where it is coming from, and why I keep finding it in all domains outgoing and incoming email...

Mine was set to 3. I have since increased it to 5. I will update this thread in hopes that it also benefits OP.

Hey just want to include that I too have received this: Mar 17 15:59:11 mailgate postfix/smtpd[1005394]: connect from vps-5730229.nextfranquias.com.br[162.214.174.112] Mar 17 15:59:12 mailgate postfix/smtpd[1005394]: Anonymous TLS connection established from...

You definitely shouldn't have it open to the world. Ensure your NAT/Port-Forwarding rule is configured so that it only permits traffic on port 26 from your external mail server. If any other address tries to send mail or traffic to port 26, your firewall should drop those packets/traffic.

Found this thread I am also needing to get this configured. Example network I think both @dthompson and I are trying to get done. I was running into the same issue with you @dthompson, I could send and receive from Mailserver to External Mail Server, but sending to other domains from "External...

So this is how it should look in Active Directory tree: ROOT AD - TEST.COM Company Folder TESTAD - Folder should contain global security group TESTGROUP Folder containing users - TESTUSERS User1 User2 Now make sure all your users are added as "members" of TESTGROUP Now the LDAP filter...

Great post, thank you for this it really helped. If anyone needs a way to filter only specific users from specific groups, this is how I got it to work. When configuring the sync options for Active Directory, under "user filter" use these search parameters...

In case anyone is reading this and having the same problems and want to do the same thing this is what I ended up doing. I moved my LXC container to the separate RAID span. I am using a Dell Poweredge with Open Manage (OMSA) installed. i was able to login to my open manage server panel at port...

Got it, so let me get this straight... dev/sda/ has mounted partition dev/sda3, that holds the local-lvm, with "discard", while the lvm-thin data2 (dev/sdb) pool i created, wasn't mounted with "discard" which is why the pool is consistently filling up? Did I get that right? So is there a way I...

So I was able to successfully backup to my NAS and run the pct fstrim command. This cleaned up my LVM-Thin. However I am still very confused as to why this LVM continues to grow and grow and grow when I am not adding any data to my only LXC container that lives in this LVM-Thin...if you see...

What would be a preferable storage type for a single lxc-container with a fixed size? Seems like lvm-thin would just be an infinite headache to manage this. Should I format the storage pool and make it into a "Directory"?

Thanks again man. I am currently doing a backup of the container to a NAS. Once the backup has completed i will give that command a shot and return with the results. Once again I appreciate you taking the time to respond and your assistance. Cheers!

I appreciate this information a lot, thank you. Where can I find the "discard" checkbox you're speaking of? Looking at the various options for the lvm-thin datastore and the container itself, I was unable to find any of this configuration. Is there anyway I can save this lvm-thin storage? Or...

I have two RAID-10 spans configured on my server (4 x 1TB HDDs per RAID 10) One stores the local and local-lvm (2TB storage) The second span I turned into its own LVM-thin storage, i called it data2 (2TB storage) On data2 I've created only one container. I wanted my data2 lvm-thin to only...

Christ! Thanks man, I could not wrap my head around that. I was getting so confused when near the drop down it said "Could not find any entries in the database", and I figured it stored email addresses that passed through the proxy and my mailserver has been up and running by sometime, so I...
