{Disarmed} Re: New server setup, best practice?

If you need the xtables-addons for geoip blocking, it is a major PITA with Centos 7 or RHEL 7.  You might want to stick to Centos 6.8

Just my 2 cents for whatever it is worth.

Subject: {Disarmed} Re: New server setup, best practice?

How:

find /path/to/files* -mtime +5 -exec mv {} \; /path/to/destination 

That would be one way.

Where: Depends on the situation. Sometimes it’s from SSD to HDD, sometimes it’s from local HDD to remote NAS using NFS or CIFS.

Best? I like CentOS 5 best just because it remained pretty much the same for over 10 years.

That being said, CentOS 7 would be the way to go; you just need to know where to put things.

Thanks Alex!  How/where do you move the mail older than a couple of days ?

What would be the best distro to use, CentOS 6 or 7 ?  I read earlier that CentOS 7 broke quite a number of conventions but support wise 7 seem
wise ?

Again, depends so much on the specific circumstance… I just set up a $5/month VPS with it, with 15GB total space, storing only the past couple of days’ worth of e-mail for a handful of users.
I’ve also set up systems for thousands of users, with a terabyte of SSD storage for “local, recent” stuff plus mbox-purge processes exporting stuff to a couple of dozen terabytes of local HDD storage and monthly processes moving
stuff elsewhere using NFS and/or rsync.
I’d rather mount NFS than SMB for performance/permissions reasons.

The choice for CPU/MEM/storage is easy when it's a virtual machine, can move around as needed. Was curious what the recommended disk size is for a MailScanner machine and what people do with archive copies of mail/spam. Mount
an NFS or SMB share to store that or something else?
Thanks :)

     It really depends on context. Space, CPU and I/O issues can vary greatly from site to site.
     If you want to upgrade, look into your biggest bottlenecks first. Sometimes it’s RAM, sometimes it’s disk I/O (where SSD’s would be great), sometimes it’s CPU
     power.
     In my case I usually go for SSD’s for storing the OS, programs, and mail - and regular hard drives for things like quarantines and such, with scripts moving older
     stuff with various protocols (NFS, rsync, FTP) over to long-term storage to make space when needed.
     Oh, and it’s not “virii”. Virus is a “mass noun”, like “rice”.   <http://t.sidekickopen62.com/e1t/c/5/f18dQhb0S7lC8dDMPbW2n0x6l2B9nMJN7t5XZsQByMPN7d-5TTRYFRKW7fsH1M56dwbYf6CVDXz02?si=5887134288314368&pi=AC798462-9730-42E6-A7E2-F18959B4CE5A&t=https%3A%2F%2Fen%2Ewikipedia%2Eorg%2Fwiki%2FPlural%5Fform%5Fof%5Fwords%5Fending%5Fin%5F%2Dus%23Virus> MailScanner has detected a possible fraud attempt from "t.sidekickopen62.com" claiming to be https://en.wikipedia.org/wiki/Plural_form_of_words_ending_in_-us#Virus

     Hi list!
     I would like to upgrade the servers that are running MailScanner.
     What is the best approach on storage? It will be virtual machines (which i guess is what a lot of people are doing now), how to approach the storage issue,
     what would be the best approach / design? What size for the MailScanner root partition etc. ?
     I have to keep verbatim copies of anything that goes in or out of the mail servers, i keep the qf/df pairs from sendmail.
     I read some people seeing their quarantine getting filled with 7 Gb of virii just in one day, what would be recommended storage sizes and how to deal with
     quarantine / archive folders? If it wise or recommended to mount an external volume at /var/spool/MailScanner/quarantine and
     /var/spool/MailScanner/archived or is  there a better way ?
     If I have several MailScanner servers, is it OK to keep all spam/archived copies in one and the same mount ?
     Will CentOS 7 work flawlessly? Anyone using standard cloud images?
     Thanks for any tips / suggestions :>)
