I am using roundcube for my email client.
My datacenter set up my dedicated server with /home having 1.8TB
The rest of my system is 20GB.
I already moved my databases.
Will I run out of room for my emails?
Were are emails stored and attachments?
If you’re using Virtualmin default settings (and you need to specifically change configuration to modify it), emails are stored in users’ home directories under /home/DOMAIN/homes/USER. So your 1.8 TB should more than suffice for a huge amount of emails and attachments.
