    Was up all night trying to figure this out but it just aint happening. Soooo close... Email works when I login to roundcube (ssl too) but when I try to connect via outlook or thunderbird it just fails.

    When I telnet/openssh from the host computer it works:
    telnet xxx.xx 143
    openssl s_client -crlf -connect xxx.xx:993
    When I try from a different computer it fails.

    Have you set up the correct DNS records to connect to your server?

    as of right now I have 2 sets of dns records. those in godaddy and the ones in ispconfig. for the ones in godaddy I have 4 A records pointing to my ip, 2 NS records pointing to the ones godaddy provided and an MX pointing to my ip. in ispconfig I have 3 a records pointing to my internal ip, my NS records point to the godaddy ones and my MX points to

    I saw you sent me a PM. Please keep the conversation here so others can help aswell.

    Why are you using a zone with GoDaddy and in ISPConfig? This can lead to confusing situations, so you should only have the zone on the nameservers you use..

    If it's not a dns issue, next thing to look at is that your firewalls (local and network) and port forwards are correct.

    Th0m... OK, I just didn't wanna advertise my numbers... There is no reason for the double dns, it was just the default settings that ispconfig setup. I haven't had the time to sit down and configure them yet :) So your saying I should only have the mx records on the active name server? or are you saying I should get rid of the ispconfig zone all together?

    Jesse... you got it, I double checked my firewall but I couldn't see anything that stood out. something told me to turn off fail2ban and BOOYAH, it started working... Now I just need to figure out why it was banning me. Much Much Thanks.

    I have to say this is a great forum and excellent product thus far... I'm excited... Thanks again folks.

    If you aren't going to use ISPConfig for your nameservers, remove the whole zone.

    You can view the banned IP list:
    fail2ban-client status dovecot
    and unban:
    fail2ban-client set dovecot unbanip
    (replace the jailname and IP with the correct jail and IP)
