We are missing this basic feature now for a very long time.

Must have!

Still waiting for this function!

Must have!!!

definitely a must have in 2016!

Must have as a webhosting provider!

Must have!!!

This is one of those "why is it not a standard feature already" requests? Come on Odin. Three years, plenty of votes and it is common sense type need.

Weird that this feature has not yet found its way, despite it being so fundamental and necessary.

i was very surprised that plesk don't have this feature, because you will find it in any other hosting-app. it is also very easy to implement, because the sender receives an email notification. so you can only bcc this mail to the mailbox owner. later on it would be nice to notify when it is almost full also.

now there are 407 votes after how many vote plesk development will think of adding it

This would be a really nice feature. Is there another way of making this happen for now? Or should we really wait for the feature?

This is a must-have item.

Is plesk development taking this feature in consideration? to still they are thinking on this request

Please bring this feature!

I'd like to write a script but it doesn't seem possible via the XML API since that annoyingly only returns the size of the mailbox but not the available size. It seems it can be done via IMAP interface but that would require each account's password.

Maybe a better (simpler) solution is for the Plesk API to return more useful information. Perhaps a request for all mailbox sizes and usage. That way we can at least script it - which I'm happy to do and stick on Github for everyone.

does any one made manual script to send mailbox

Interesting to see this feature is still being discussed nearly 3 years after we first proposed it. Yesterday a client called to say they had not received email for 24 hours and the problem was their mailbox limit had been exceeded. Checking the mailbox we received notification but the mailbox owner was oblivious.

This seems crazy that as the server admin I receive an email to say the mailbox is full, everyone who sends an email to that mailbox gets informed the mailbox is full but the mailbox owner has no idea. So I need to manually contact the mailbox owner to tell them their mailbox is full and ask them to remove some email (or up-sell more space) - this is surely not a complex problem to resolve - just inject a configurable warning message to their mailbox when they reach X% from their allocation.

@ Anonymous: Thank you too.

I agree on the first two questions you asked.

My perception is that most hosters today offer hosting packages with size limits. The more capacity they offer the more they cost. So, it's quite common that mailboxes are limited in size and that they sometimes reach their limits. Please comment if your perception is different.

Here is my practical experience so far:

- Customers complain if they are eventually told by senders that their mailbox is full. All to often must they empty their mailbox or upgrade it to a larger size first before they are able to receive emails again. They lose some emails, too.

- On the other side, they are happy if their mailbox notifies them at - say - 80% of its capacity. (One of my hosters has implemented a script that does this.) For the customer it's "a stitch in time saves nine."

Consequently, I would be in favour of customisable softlimits for mailboxes on Plesk that trigger a notification, as well as default thresholds per server/domain that hosters/admins can customise.

Example:
[x] Notify me daily when [ n ] % of mailbox capacity has been reached.

And I am always open for other suggestions that make customers happy.

@ dave: thank you for discussing this with me, here :)

so you agree with me that the definition of what may be large depends on the configuration of each system involved. would you also agree with me, that it depends as well on the era in which we live? what was large in 1996 was not large anymore in 2000; what was large in 2000 was not large anymore in 2008.... and tody we have 2016. What we estimate as large is not limited by smtp design, but rather on individual purposes, expectations, resources, etc.

btw i am convinced the internet was not "designed" to allow bored housewives and children to entertain themselves by streaming tv sitcoms over their 3G/4G network. what a waste of precious resources! what a damage to environment! what dangers for our health (from radio emission, chemical pollution...). but technically/by design, it causes no problem, so we do it.

i agree with you that a 10MB may be annoying, a 25MB certainly is for me personally, but it passes smoothly in my infrastructure. but by discussing this we ould drift off topic.

what want to point out with all this: what is essential for a mailbox owner, is: as long as there is enough space for delivery of a message, then there is no problem and as such no need to be notified. the need only arises the moment when there is a lack of space. which can never be told upon an (arbitrary!) softlimit.

we should not impose subjective opinions about size on others, and let the resulting system be timeless :)
