1. Have you script for create emails in  iRedmail Pro from command-line or CSV (email; plain password; description;)
2. I am create some emails and users want to rename it (to recreate these email inconveniently of shopping mall they are signed on many lists of mailing list (aliases), have many settings in RoundCube and have letters in mailbox). In web-intarface of iRedAdmin-Pro i dont find this feature
3. Have you "search tool" in this forum? (http://www.iredmail.org/forum/forum2-ir … pport.html) Maybe this question already was discussed?
Thank you beforehand.
