I've been using Dovecot with Sieve for a long time already, and I'm very happy with it. Push is working fine too. I was wondering, however, whether it would be possible to define a Sieve rule (perhaps using some plug-in), such that an IMAP push message gets sent out only for specific senders etc.?

I think you cannot.

But you could split your INBOX into senders with PUSH (that are delivered to the INBOX) and others, that are delivered to INBOX2.

perhaps the imap lemonade extensions may do that ....have you investigated by that?

Thanks, that's interesting -- two questions:

1. Why is it not possible? Just not implemented, or is there any technical reason that actually prevents it from being implemented?

Because the current implementation of IDLE signals any message to the waiting client.

2. What do you mean by INBOX? Another, completely separate email account? Yes, that would be my backup plan.

When your client IDLEs, it monitors just one particular mailbox, say INBOX, top.sub.sub2.box, or whatever. So, if you have your client IDLE (monitor) INBOX and have all senders delivered to yet another, newly created mailbox (mail folder, ..., _not_ another mail account), which is not monitored with IDLE, you get no PUSH for them. You have to pull them.

Did you've read Robert's answer about LEMONADE? Maybe ESEARCH and NOTIFY do what you want, because RFC5465 / sec 5.2:

" If a search context is in effect as specified in [RFC5267], an ESEARCH ADDTO will also be generated, if appropriate. In this case, the EXISTS response MUST precede the ESEARCH response. Both the NOTIFY command and the SEARCH and SORT commands (see Section 7) can specify attributes to be returned for new messages. These attributes SHOULD be combined into a single FETCH response. The server SHOULD avoid sending duplicate data. The FETCH response(s) MUST follow any ESEARCH ADDTO responses."

You could flag "priority" senders in Sieve and let you notify for new messages with that flag. How well or if at all Dovecot supports this (and your client ;-) ), I don't know.

kind regards,
