*) Currently you can use tool script shipped in iRedMail (create_mail_user_*) to import (or bulk create) users. What information do you use while importing user? Just email address, password and display name?
Can I create all new mail accounts at the same time with CSV file ?
*) iRedAdmin-Pro doesn't support export mail accounts yet. May i know what information you want to export?
Can I save exitsting mail accounts which I create in excel file? So, I need to export.
From iRedMail to Gmail? This doesn't make much sense to me. There's no software will delay the mail delivery in iRedMail for OUTGOING email, but still some possibilities:
*) You have a slow DNS server. If DNS query takes long time, it will slow down the mail flow.
*) There's something in your network.
Anyway, you have to check Postfix log file to figure out why it's slow.
Yes, iRedMail to Gmail. We buy dns from godaddy.
