How can I increase the maximum size of an email with the build-in SMTP?

[Vladimir]

Hello,
Currently, I can't send emails with attached files bigger than 20/25MB. How can I increase this?

@Vladimir Currently, this value is hardcoded. 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.

Okay thanks

@girish Not to sidetrack but this is probably another great example of where the config should be exposed in the Cloudron UI (and of course persisted), related to many of the email improvements many of us are waiting to see in the near future.

I have added this in the 6.0 roadmap to be configurable.

@girish Was this option added ?

@AartJansen Yes. It's in your dashboard > Email > Settings > Maximum email size

@humptydumpty Thank you! I tried to find it, but wasn't doing a good job.

I have nothing to add here, but I am curious. 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?

@Stardenver yes, much better to use things like wormhole.app for GBs of gifts to send.

@robi or even Jirafeau which is available on Cloudron and does the job nicely.

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).

@Stardenver Well I had a customers server that he wanted the mail limit upped from 40Mb to 60Mb... and I thought I had done that, but couldn't send a big enough email to test.
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.
