Original GitHub issue: https://github.com/jberkel/sms-backup-plus/issues/1074

Originally assigned to: @kurahaupo on GitHub.

Expected behaviour

Restore all backed up SMS from a 4.x Android to a new and empty 10 Android (LineageOS, /e/), using custom IMAP server.

Actual behaviour

When restoring, identification step passed, then stopped with a UID SEARCH 1:* (HEADER X-SMSSYNC-DATATYPE "SMS") UNDELETED; response: #4# [BAD,UID SEARCH bad parameters] message

Steps to reproduce the behaviour

Save all SMS from the 4.x Android phone with custom IMAP configuration in the "SMS" folder (the save settings left as it is)
Install the app on the new phone (/e/ OS on Fairphone 3)
Configure IMAP settings
Launch recovery

Please specify the following:

Android version : 10 (Lineage OS /e/)
Phone model / brand : Fairphone 3+
SMS Backup+ version installed : 1.5.11
Messaging app : (please specify the software that you usually use to read & send SMS & MMS messages)

sms_backup_plus/.log is empty

Have you set the IMAP "folder" (Gmail "label") to match the previous installation that you want to restore from?

If not, it's likely that there are no messages in the folder/label that's actually used, so that the range 1:* is invalid, because there's no message numbered "1".

I have a similar problem, where the server logs show: Error: FTS Xapian: Unknown header 'x-smssync-datatype'.
Perhaps it would be useful to support iterating items without relying on this header being searchable.
