Maximum mailbox size and attachment limits
Posted: Wed Apr 22, 2026 8:52 am
Hello everyone,
Iām 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.
