Email restrictions

To ensure a good user experience and users safety, the following restrictions apply on sending and receiving emails.

Sending e-mail

It’s allowed to send 1 message every 5 seconds from Zone’s outgoing (SMTP) server and webmail. If the limit is exceeded, outgoing messages will be automatically blocked. To remove the limitation, contact our customer support.
You can find more info about e-mail server limits here.



Spamming from our servers is strictly prohibited. Emails containing advertisements that customer hasn’t ordered, are considered as spam.

In this matter we are governed by the Law of Obligations Act that states:

§ 60.Restrictions on use of means of distance communication
An offer may be made to a consumer by automated calling systems without human intervention, fax, telephone answering machine or electronic mail only with the prior consent of the consumer. Other means of distance communication which allow individual communication may be used for communicating an offer only if the consumer has not expressly forbidden the use thereof.

Message quota

Maximum size of sent and received email message is 25 MiB with headers. When sending an email, bear in mind that the size of added attachment increases by 30%.
Example: If the size of an attachment is 10 MiB, then the size of an email will be around 13 MiB (attachment plus header and message content).

Mailbox quota

Maximum mailbox quota depends on the Web-hosting package.
There is a possibility to raise the mailbox size to 50GB or 100GB, for which you can find instructions here.


Do not open emails containing suspicious files. Consider if the sender has any reason to send such emails. If you have any suspicions, then contact the sender by phone and check if it was he who sent the email.
