Mailserver Authentication

Gmail outbound mail requires reauthentication through Captcha

How often does JEMH Cloud poll message sources looking for new emails?

The rules depend on if the message source is online/offline (connection, authentication problems, etc), the configured interval and when was the latest message processed. 

Given the user interval in minutes (default is 1 minute) current strategy is:

How can I know which messages JEMH Cloud has sent?

You can tag  JEMHC's email subjects with a Subject Prefix (like [JEMHCloud]) to you Message Outbound configuration (Messages -> Message Outbounds -> Pen/Edit Icon).

How can I restrict how many emails can an user sent to JEMHCloud?

If you want to restrict a particular email address, you can do it going to Blacklisting -> Blacklist by Email Subject.

If you want to restrict users about how many emails they can send to JEMHCloud, you can set an hourly limit going to Profiles -> Your Profile -> Cog ->Edit and set up 'Sender is Bulk' message threshold. If the configuration is 3 (really low),

when JEMHCloud receives processable messages (valid addresses, no blacklisted, match catch, no procedence:bulk) what's happening is the following:

10:00 am theuser@mail.com processed (1 in the last hour)

10:10 am theuser@mail.com processed (2 in the last hour)

10:10 am somebodyelse@hotmail.com processed (1 in the last hour)

10:45 am theuser@mail.com processed (3 in the last hour)

10:50 am theuser@mail.combulk action taken (4 in the last hour)

11:20 am theuser@mail.com processed (3 in the last hour, first 2 don't count as they happened over 1 hour ago)

11:25 am theuser@mail.combulk action taken (4 in the last hour)

11:25 am theuser@mail.combulk action taken (4 in the last hour)

12:30 am theuser@mail.com processed (1 in the last hour)

How is the plan's data affected after processing an inbound email?

There are 2 streaming actions from/to JEMHC when processing an email. The first action is downloading the email from your email server. The second action is uploading every email attachment to your Jira or Storage instance.

As an example, if there is an inbound email to be processed with 2 attachments:

The data cost of processing this email will be:

This 2.5+ MB will be counted toward your monthly plan or removed from your data pack if you have used all your monthly plan. 

How is the plan's data affected after sending an outbound email?

There are 2 streaming actions from/to JEMHC when sending an email. The first action is downloading the related attachments from JIRA. The second action is sending the emails with the attachments to each recipient.

As example, an user updates a Jira issue adding a 1MB attachment. There are 3 email recipients

The data cost of sending this email will be:

This 3+ MB will be counted toward your monthly plan or removed from your data pack if you have used all your monthly plan. 

JEMHC tries to send an email to multiples recipients when possible saving data usage and processing time. This cannot be achieved if:

In the example JEMHC was able to save data by sending the same email to both watchers. But it had to send another email to the Assignee as the email body is different (by default there is a 'Your Role Assignee' label in the body of the email).

What is the standard for Email Content structure, address structure, distribution list structure

6.2.6. MULTIPLE MAILBOXES

   An individual may have several mailboxes and wish  to  receive
   mail  at  whatever  mailbox  is  convenient  for the sender to
   access.  This standard does not provide a means of  specifying
   "any member of" a list of mailboxes.

   A set of individuals may wish to receive mail as a single unit
   (i.e.,  a  distribution  list).  The <group> construct permits
   specification of such a list.  Recipient mailboxes are  speci-
   fied  within  the  bracketed  part (":" - ";").  A copy of the
   transmitted message is to be  sent  to  each  mailbox  listed.
   This  standard  does  not  permit  recursive  specification of
   groups within groups.

   While a list must be named, it is not required that  the  con-
   tents  of  the  list be included.  In this case, the <address>
   serves only as an indication of group distribution  and  would
   appear in the form:

                               name:;

   Some mail  services  may  provide  a  group-list  distribution
   facility,  accepting  a single mailbox reference, expanding it
   to the full distribution list, and relaying the  mail  to  the
   list's  members.   This standard provides no additional syntax
   for indicating such a  service.   Using  the  <group>  address
   alternative,  while listing one mailbox in it, can mean either
   that the mailbox reference will be expanded to a list or  that
   there is a group with one member.
