Is there a known documented way to copy messages from backup folders
into the cur folder and have them not make a mess of the dates. What I
see is if I copy several year old messages to the cur folder on an
ubuntu box the massages when viewed on an android phone appear out of
order. I tried deleting the dovecot index and cache files and restarting
the service, I also tried running these 2 scripts I found. I added some
echoes to see what was occurring. Still, messages appear out of order
and some do not appear at all on the droid.
I tried copying the actual message files out of various cur dirs and
still some were very out of date. The second script seemed to be
adjusting the dates of the files properly, but I am not sure what
android gmail actually uses to sort.
#!/bin/bash
for i in `ls /home/brian/Maildir/cur/`
do
? # Find the date field and then remove up to the first space (Date: )
? DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1
--complement)
? # Create a timestamp from the date above
? STAMP=$(date --date="$DATE" +%Y%m%d%H%M)
? # touch the file with the correct timestamp
? touch -t $STAMP $i
? echo "$i stamped"
? echo "$DATE"
? echo "$STAMP"
done

#!/bin/bash
# Fix emails with bad timestamps in a maildir
# This script reads the date from the email header and set its UNIX
timestamp and renames it with the proper date
# e.g. this:
# dec.? 05? 2017
1512499812.M908995P21566.ip-111-11-11-11,S=16331,W=16746:2,S
# becomes that (the email Date header is "Date: Tue, 22 Oct 2013
10:07:21 +0100"):
# oct.? 22? 2013

cd "/home/brian/Maildir/cur";
for i in `ls? 1482809425.M277770P17438*`
do
? echo "$i"
? # We extract the date from the email headers
? DATE=$(grep '^Date:' $i | head -1 | cut -d' ' -f1
--complement)
? # We compute a touch-compatible timestamp as well as the real timestamp
? TOUCHSTAMP=$(date --date="$DATE" +%Y%m%d%H%M)
? TIMESTAMP=$(date --date="$DATE" +%s)
? # We set the file timestamp
? touch -t $TOUCHSTAMP $i
? # We rename the file with preprending timestamp
? newfilename="$TIMESTAMP.${i#*.}"
? mv "$i" "$newfilename"
? echo "$newfilename"
? echo "******"
