Customer email notification when mailbox quota exceeded
It would be a very useful feature to have an email automatically injected to a customers mailbox when their quota is close to the limit and another when the mailbox quota has been exceeded with advice (customisable) on how to resolve the problem.
Sometimes clients are unaware/forget their quota and if accessing via outlook/smartphone etc they are not aware of the limit being reached. This can result in several days without emails or emails being rejected with a "mailbox full" autoresponder. Ironically this means anyone sending emails to the client are aware the mailbox is full but the client is unaware of the problem.
@ 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 :)
@ Anonymous: Sorry, I forgot to mention that by "large" attachments I mean those of over 10 or 25MB. Some web based email providers such as Gmail, Hotmail and Yahoo have such limits, so the success of sending/receiving larger messages depends on the MTAs involved in each case. My general impression is that messages up to 10MB pass without any problems.
Yes, it can be evaluated if it is more useful to send a notification before or after a message is rejected (or both). The main thing in my view is that Plesk mailbox users get notified.
Thank you for your contribution and your vote. Let's hope that Odin will realise this feature soon.
@ dave: if god had wished for man to be able to fly, he would have given him wings ;)
if smtp was not designed for large (that is...?) attachments, then it should not support them.
but it does. and peaople do use it. and it does not make problems if no other specific error occurs. and so, accompanying mechanisms should respect that fact. and i think, my proposal is more 'generic' than defining an arbitrary 'softlimit' and waiting until that softlimit has been overshot.
@ Anonymous: Quota rejection can indeed happen at any capacity. However, email architecture is not designed for large attachments (yet), so I would like Plesk to cover standard cases of average email message sizes. Mailbox owners / administrators should be empowered to make the choices on the configuration settings themselves, such as deactivate/reactivate notifications or modify the notification threshold.
i understand the primary urge for this feature. but the problem is: quota related jejection of a message can happen at any mailbox capacity occupancy / remaining capacity. it just depends on the size of the specific message itself.
so, i would rather suggest to notify the mailbox owner in each case of quota related rejection - if limited to a number, then at least once a day. the notification message could of course contain capacity occupancy details.
for security reasons, the message should NOT contain any hyperlink (e.g. to plesk). users should not get accustomed to click on links provided in unexpected and non-personal mails. such mails could too easily become spoofed to persuade recipients to download malware or to reveal smtp credentials to third party.....
pleaso also consider that this notification issue should currently not be too urgent anymore, since, as i was told (situation: plesk 12.5 on ubuntu 14.04 with dovecot), modern clients can communicate with the server about the quota/capacity, and display it 'in-app'. is this valid for pop3 too, or for imap only?

is plesk going to implement feature of "Customer email notification when mailbox quota exceeded"

i am surprised from 2/5 years this request is under review, people like us who are doing shared hosting business need this feature'
This feature is not special feature which required voting, it is standard feature which every mail server has
We are using Cpanel and Hosting Control has this feature
Please implement this, this would be really helpful.
yes, this would be a nice feature, requested by many of our customers!
Sorry, but whether you can accept the argument or not - we can only sort requests by amount of votes, not by amount of "please!" or "urgent!" comments.
Each user can allocate 1 to 3 of their votes for a request. The more people vote, the more votes they allocate in average - the higher would the rating be, the more attention request will receive.
I would not complain, but it's hard to accept this argument: there are a lot of started suggestions with fewer votes.
That's actually why we have voting here. While this request is very important to you guys, but there are 10 other requests with higher votes. Perhaps some of you even dedicated a share of your votes to those other requests as well.

Very urgent feature! Come Odin | Plesk, 2 years under review. Really?
Would really appreciate if the Plesk developers can dedicate some time into adding this feature :)

This is needed! but needs a bit more to it. in the event that a email account is set to unlimited the uses or domain owner need to get an email IF the one email account is running on and using the quota assigned to the sub.

This is certainly a very important feature. And yes: this is a standard function on all professional maintained mail servers as far as I know ... URGENT !!

At least a simple list of the affected mailboxes would be very helpful!
