<![CDATA[How can I increase the maximum size of an email with the build-in SMTP?]]>Hello,
Currently, I can't send emails with attached files bigger than 20/25MB. How can I increase this?

I have no idea why they 'need' it, its usually some self-employed boss who doesn't know better, or can't be told.
I make the changes they ask for, and charge for my time.

I use that, but also have greatly increased the maximum too because sometimes I e.g. want to email a large ebook to Amazon to automatically get it on my Kindle (although sometimes it's too large and Amazon reject it at their end - need to check what their max is).

Whats the reason for doing such? I can imagine that most other providers will still reject your mail due to its big size. Wouldn't it be easier and better to upload those files and share the link?

I tried to find it, but wasn't doing a good job.

It's in your dashboard > Email > Settings > Maximum email size

docker exec -ti mail /bin/bash .
Then edit /run/haraka/config/databytes. Currently, it is 25MB (26214400).
supervisorctl restart haraka

Okay thanks

Until we make it configurable, what you can do is to SSH in the the server and:

  • docker exec -ti mail /bin/bash .
  • Then edit /run/haraka/config/databytes. Currently, it is 25MB (26214400).
  • supervisorctl restart haraka

Unfortunately, the above value is not persisted across server reboots.
