Re: [MlMt] Moving complete folder tree from one IMAP server to another

Thank you for the recommendation.  I did get it to work.  It ran quite 
slowly, but I suspect I was being throttled by Gmail.


When I last moved my own email from a small but well-run ISP, I did see 
3.8MB/sec from them, but Fastmail topped out at just 872KB/sec (but 
didn't stay there).  This was done from where I work, and have an OC-3 
(about 18MB/sec) connection on Level 3's network (one of Fastmail's 
peers).  I'd guess that Fastmail, more so Google mail, are fairly 
heavily loaded.


I did have a problem with a memory leak.  So I had to kill it and 
restart it a couple of times.


It's been a while since I last used it, but I haven't had any any 
trouble with the precompiled Darwin version.  A typical command line (my 
needs are simple, heh) -


./imapsync_bin_Darwin --host1 Skipper.Opus1.COM --user1 bi...@mix.org 
--password1 MASKED --ssl1 --host2 mail.messagingengine.com --user2 
bi...@mix.org --password2 MASKED --ssl2 --tmpdir /var/tmp


And the results -

Total bytes transferred   : 3383047221 (3.151 GiB)
Average bandwidth rate: 225.2 KiB/s
Memory consumption: 2737.7 MiB

Indeed :)

It is an open source tool - with the typical paid for support if you 
need it (you probably won't unless you have a non standard migration to 
perform).

I did have a problem with a memory leak.  So I had to kill it and 
restart it a couple of times.  I was moving a 2GB mail account and it 
grew to over 25GB with less than 20% done.  I found a recommendation to 
use the “-useuid” option which made it grow much more slowly (I 
still suspect a memory leak - just a much smaller one). I do agree it is 
a very powerful tool.

Yes, I've used this a few times, and highly recommend it.
