Yes I did stop and start the mysql service after the install, the service started without error.

thanks zhang
no it is the same, when I access roundcube   the page loads and i get database error : connection failed and when accessing /iredadmin i get an internal server error

I have tried adding bind-address=, skip-host-cache, skip-name-resolve to my.cnf and restarting but no success
I can log into roundcube db via cli using username and password from iRedMail.tips file and also iredadmin db using details from iRedMail.tips

I see this error in maillog when accessing roundcube

Thanks Zhang , no i didnt install using the below command . So I started again by creating a new jail I have been using iocage for creating the jails  and run through the install instructions for the jail installation using LOCAL_ADDRESS='xx.xx.xx.xx' bash iRedMail.sh . I am still getting the same errors as the previous jail when accessing /mail and /iredadmin

i see this in the uwsgi-iredadmin.log when accessing /iredadmin

OperationalError: (1045, "Access denied for user 'iredadmin'@'mx2.xpressmail.com.au' (using password: YES)")

and this in the mail.log when accessing /mail

Thanks Zhang
I used the ip of the jail 10.1.1.5 for the LOCAL_ADDRESS. I followed the tutorial but not strictly as I am using iocage not ezijail . But followed through and used commands for iocage. I must be missing something from the tutorial to cause these issues as my previous installs using Debian have been no problem at all.Im switching my servers across to FreeBSD and using jails so I need to get this working before I make the switch for my running iredmail server. Thanks for your help Zhang .

Thanks Zhang
I want to use with iocage so I will try to work out the reason this dosnt work, I have tried with postgresql as well with same result. I will do a clean  install on 10.2 freebsd without jail to see results  . If any others are familiar with iocage please chime in I am open to suggestions to get this working. Thanks

I have iRedmail mysql working in iocage jail , but Im having problem installing ldap version which is the version my pro licence is for. I have the below error when running install script. I dont see py-ldap2 in the ports only py-ldap3. thanks
   
/root/iRedMail-0.9.2/functions/packages_freebsd.sh: line 1031: cd: /usr/ports/net/py-ldap2: No such file or directory
make: don't know how to make clean. Stop

Thanks Zhang
The install completed correctly and it is up and running in an iocage jail, the host server has low memory so once I have finished testing I will need to increase the memory size for the vps. Thanks again  for your help
