Maximum mailbox size and attachment limits

Post by samba »

Hello everyone,

I’m currently setting up my email on TuxMail and I have a question about the technical limits of the service.

What are the current limits for:

Maximum mailbox size per account?
Maximum email attachment size (incoming and outgoing)?
Are there any additional limits per domain or per user (e.g. number of aliases or mailboxes)?

I want to make sure I understand the constraints before configuring everything for a project.

If someone from the team or an experienced user can clarify the current limits and any recommended best practices, that would be really helpful.
