Search (IMAP): Unknown search criterion: BEFORE

[basbebe]

I have set up an IMAP backend and I know that dovecot's its with lucent works in it.

However, z-Push doesn't let me search from my iPhone.

This is what i get in my logs:

I would say that your IMAP server doesn't support the BEFORE keyword https://tools.ietf.org/html/rfc3501#page-49

You can test it executing manually the SEARCH. This page explains how to do it: https://www.skytale.net/blog/archives/23-Manual-IMAP.html

[basbebe]

I checked and my IMAP server does understand the BEFORE keyword. However it doesn't understand the Date specification as it seems: 2015-12-06T02:15:18.000Z This one works: 2015-12-06 http://wiki2.dovecot.org/Tools/Doveadm/SearchQuery#section_date_specification

[fmbiete]

The referenced commit should fix the issue. We will discard the time/timezone information since it's not really useful and will break.

Let me know if it works.

[basbebe]

Search works now, thank you! However, I see in the logs that dovecot returns the search results pretty quickly but it takes a really long time for them to appear on the device. Is that normal behavior?

[fmbiete]

Yes, that's normal. The device has to parse all the messages found and is not really fast (even with the quad-cores, phones are slow).

Thanks!
