Hi everyone. We use iRedmail in my company since 6month.
My CEO have some problem with SOGo. When he connect on the webmail, he got a "timeout expired"... He has like, 25000 mails in INBOX...
He don't want to clean his mailbox, so i wanted to know if it's possible on SOGo to activate some "page system", or something like that ? (Like 100mails per page)
I find nothing on the web, so i need your knowledges
