Sorting order in splitting target groups

Sorting order in splitting target groups

[Pankaj Jangid]

I am using IMAP. And the sorting order in the INBOX folders is
chronological i.e. the latest emails are at the bottom. But I am also
using splitting rules and most of my emails end up in other groups.

In those groups which are target of splitting, the sort order is
reverse chronological i.e. new mails are at the top. And within a thread
also the order is reverse chronological. Like this,

--8<---------------cut here---------------start------------->8---

When it is reply in a thread, these are properly ordered, except a
few. I don't understand the logic here. Please somebody explain this to
me.

Look at line 18, this is a reply to a a future email. Line 20 is also
reply to a future email.

Even if it is not a thread, the order is reverse chronological.

Inbox is chronological. Like this,

--8<---------------cut here---------------start------------->8---
28     Today, 02:02     [  27(5.1k):automatic@2checkout.com] Online Order Notification #283
29     Today, 02:02     [  27(5.1k):automatic@2checkout.com] Online Order Notification #283

My question is: Is this possible that I am doing something wrong to mess
up with the sorting order /or/ is this the default sorting in splitting
target groups? If it is default then what is the logic?

Work on it for sometime. And found that the article numbers generated
are not in the order of article date. And the value of my
`gnus-thread-sorting-functions' is default.

Its value is (gnus-thread-sort-by-number)

Is this something that is related to IMAP? Probably IMAP is sending
articles in random order and Gnus assigns them numbers in that order.

Using number, as you have found, can lead to confusing results.  Have
you tried gnus-thread-sort-by-date?

(setq gnus-thread-sort-functions
      '(gnus-thread-sort-by-number
        gnus-thread-sort-by-date))

I am using this now. There are still few case that I'll have to figure
out. But overall better now.
