we’re using NethServer release 7.4.1708 (Final) with some e-mail addresses configured. Recently something strange happened with 2 of the configured e-mail addresses which users use to view from Windows using common clients (Outlook / Thunderbird / Outlook Express). All of a sudden all e-mails disappeared both from clients and webmail. They’re not really disappeared as I can “see” them in each maildir fortunately and I have downloaded the whole folder for safety reason but I cannot understand why they’re not more visible through webmail or clients. I also noticed that even if mailboxes have no e-mail quota set when I login to Roundcube webmail I see size limit (1023MB). When I manually reloaded “lost” e-mails of an e-mail address from which messages have disappeared it soon reached the max limit so I cannot load any old e-mails. Could it be related to the problem I had with disappearing e-mails? I didn’t set up Nethserver and I’ve only inherited its management so maybe I’m missing some basic setting that I’m not aware of.
