I am currently testing the Proxmox Mail Gateway on a low priority domain before we roll out on our primary mail domain. I see the recommended specs have 8GB available storage on the server, but I can't wrap my head around how that would be enough space for a domain receiving 10-15K emails a day. I built my test machine with 50GB, but I want to make sure that when I do build the production VM I don't short it on storage. Looking through documentation and previous posts, the "User Statistic Lifetime" should be what keeps my disk usage reasonable, correct?
PMG Storage Questions
- Thread starter vix9
- Start date
The things that count towards the needed disk-space of your PMG installation:
* mails in quarantine (so these depend on your ruleset, and on the quarantine lifetimes (virus/spam))
* mails in the queue (in case you have a network error)
* statistics tables (this is dependendent on the statistics lifetime you configure)
* number of backups you keep on your local disk (for non-PBS backups)
* to a (much lesser) degree - your ruleset
all in all I would not worry too much about the diskspace - a productive instance I have access to (handling around that volume of mails you mentioned) - is not even using 20GB
Additionally you can resize the disk in most setups - and you even can restore a backup to a new larger machine without too much hassle
I hope this helps!

Using 80GB for neer 50k mails a day for 2 year, the syslog keeping from beginning and storage still under 60%
To make myself feel better I doubled the storage to 100GB. Doesn't seem like I'll need it, but eased my mind a little.
