With --gmail1 --gmail2 you can override the parameters
that are activated by them, for example:
imapsync ... --gmail1 --gmail2 --maxbytespersecond 50_000 --noautomap
Explanations:
--maxbytespersecond 20_000 ( 20 kBytes/s ) option is here to avoid
locking or errors when imap transfers exceed Gmail maximum limit.
See http://support.google.com/a/bin/answer.py?hl=en&answer=1071518
--maxbytespersecond 20_000 is not mandatory in the sense Gmail may
allow you to use an upper value than 1 GBytes per 24h without
disconnections. If you count well, it should be 10_000, not 20_000.
--maxbytesafter 1_000_000_000 option is there because
option --maxbytespersecond 20000 is unnecessarily slow if the Gmail
account size is less than 1 GB.
--maxsleep 2 is to avoid sleeping more than 2 seconds when
the --maxbytespersecond value implies a long sleep between 2 copies.
--automap is not mandatory but it's a feature to automatically
map folder names based on the Gmail user configuration itself, par account.
It will save manual folder names changes or the use of --regextrans2
or --f1f2 to map folder names.
For example, imap folder "[Gmail]/Sent Mail" may be mapped as one of
E-mails enviados
Enviada
Enviado
Gesendet
Gönderildi
Inviati
Sendt
Skickat
Verzonden
etc.
on both sides, host1 or host2, maybe differently, sometimes in
incomprehensible alphabets, a headache for imap sysadmins.
See a listing here:
http://stackoverflow.com/questions/2185391/localized-gmail-imap-folders/2185548#2185548
--exclude "\[Gmail\]$" is just there to avoid a warning error
when selecting this not used folder.
Be aware that --gmail1 --gmail2 is a special case, it's not what
--gmail1 does plus what --gmail2 does when they are not invoked
together.
