[Evolution] Evolution 1.2.2 much slower than 1.0.8 in POP retrieval

[Jeremy Coleman <jeremy coleman yoda it>]

Yesterday I upgraded Evolution from 1.0.8 to 1.2.2, (using redcarpet),
and I have suffered a severe performance degradation in fetching email
from my POP server (which contains 4800 emails).

Unfortunately, I no longer have the old version of evolution so I can't
check differences in the POP protocol messages exchanged.

However my sniffer tells me that the slow part of the process is the
processing of the LIST pop command which returns the 4800 lines with the
message ids of my emails.

I presume the old version didn't issue the LIST command because it was
far quicker. The LIST command is slow even if issued from telnet.

These are the response times:

1.0.8 version: fetched new mail in less than 10 seconds
1.2.2 vesrion:  takes 90 seconds
telnet to POP: LIST command to POP server takes 62 seconds

My pop setup has 'leave messages on server' option checked in the
'receiving options' form.

Is it necessary to issue the list command after the first access?
Shouldn't the client only fetch the messages which are subsequent to the
last fetched?

Could it be something to do with my setup? (I tried creating a new user
and fetching from a virgin environment, but the final result was the
same).

Any help appreciated, thanks.
