Imapsync tips to select messages.
|
|
=====================================
|

By default, Imapsync syncs all messages, avoiding duplicates.

|

|
Q. Is there a way we can specify an age to sync emails?
|
|
If yes, can you please share some examples?
|
|
|
|
R. Yes, with the --maxage or the --minage option.
|
|
|
|
E.1 Sync only messages less than 2 days old:
|
|
|
|
imapsync ... --maxage 2
|
|
|
|
E.2 Sync only messages more than 2 days old:
|
|
|
|
imapsync ... --minage 2
|
|
|
|
E.3 Sync only messages more than 30 days old and less than 365 days old:
|
|
|
|
imapsync ... --minage 30 --maxage 365
|
|
|
|
E.4 Sync only messages less than 30 days old or more than 365 days old:
|
|
|
|
imapsync ... --maxage 30 --minage 365
|
|
|
|
Full explanation:
|
|
|
|
--maxage <int> : Skip messages older than <int> days.
|
|
final stats (skipped) don't count older messages
|
|
see also --minage
|
|
--minage <int> : Skip messages newer than <int> days.
|
|
final stats (skipped) don't count newer messages
|
|
You can do (+ are the messages selected):
|
|
past|----maxage+++++++++++++++>now
|
|
past|+++++++++++++++minage---->now
|
|
past|----maxage+++++minage---->now (intersection)
|
|
past|++++minage-----maxage++++>now (union)
|
|

Q. I want to sync messages based on their UID.
|
|
|
|
R. First have in mind that UIDs are uniq only per folder, so work this
|
|
way only with one folder at a time, with --folder option.
|
|
|
|
To show UIDs, there is the --debugLIST parameter.
|
|
|
|
imapsync ... --debugLIST
|
|
|
|
To sync only a part of all messages, selected by UIDs
|
|
from 10000 to 11000:
|
|
|
|
imapsync ... --search1 "UID 10000:11000"
|
|
|
|
To sync from INBOX only 3 messages UIDs 20000 20002 20004:
|
|
|
|
imapsync ... --search1 'OR OR UID 20000 UID 20002 UID 20004' --folder INBOX
|
|
|
|
To sync all messages from INBOX except 3 messages
|
|
UIDs 20000 20002 20004:
|
|
|
|
imapsync ... --search1 'NOT OR OR UID 20000 UID 20002 UID 20004' --folder INBOX
|
|
|
|
If you search n UIDs then you have to put n-1 OR in the search line.
|
|
That's IMAP.
