Hi,I tried various settings, and it never does anything. Basically I have Fetching Email via IMAP or POP enabled, through IMAP, credentials are OK and SMTP server is not complaining (I have access to logs). It's set to import up to 100 e-mails per 1 minute right now. I try to do the "mass import" using Recurring Tasks Scheduler, but I also tried other ways to make sure it's not related to this particular method - it looks like it isn't.I tried looking through PHP error logs, but there's nothing from osticket. Like I mentioned before, there's also nothing in dovecot logs Some basic information about the machine:PHP Version: PHP Version 5.6.24 (behind nginx, via fastcgi, php-fpm)OS: FreeBSD 10.3-RELEASE-p3, amd64IMAP server: dovecot 2.2.25 (7be1766)Basically all crucial PHP modules are installed. I'd like not to post whole phpinfo file for security reasons, although if there's something crucial you need from it I can most likely post it.So, just tu summarize: around 17k emails from 65k total went through just fine (it took some time, but it worked as expected). At some point, probably, osticket encountered an e-mail it couldn't process for some reason - however, I don't know what that e-mail is or why it doesn't work. If I knew that I could probably come up with some workaround.Then again, I'm not sure if the way I try to import old e-mail threads to osticket is the right way to go?
