    Default Can't Accept email with TLS

    Zimbra,

    I am having problems accepting emails via tls from microsoft.

    Here are what the logs say

    Code:
    Jul  6 14:44:45 mail-1 postfix/smtpd[9266]: connect from smtp.mssupport.microsoft.com[131.107.1.44]
    Jul  6 14:44:45 mail-1 postfix/smtpd[9266]: setting up TLS connection from smtp.mssupport.microsoft.com[131.107.1.44]
    Jul  6 14:44:45 mail-1 postfix/smtpd[9266]: SSL_accept error from smtp.mssupport.microsoft.com[131.107.1.44]: -1
    Jul  6 14:44:45 mail-1 postfix/smtpd[9266]: lost connection after STARTTLS from smtp.mssupport.microsoft.com[131.107.1.44]
    Jul  6 14:44:45 mail-1 postfix/smtpd[9266]: disconnect from smtp.mssupport.microsoft.com[131.107.1.44]
    Im not sure if this is related, but when i restart my mail server I get this error

    "Unable to determine enabled services from ldap"

    also I am running my setup on DRBD


    I have checked
    vi /etc/host
    Code:
    127.0.0.1       localhost.localdomain localhost
    10.1.200.14     mail-1.example.com        mail-1
    10.1.200.15     mail-2.example.com        mail-2
    10.1.200.14     mail.example.com          mail
    Here are my dig results

    Code:
    ; <<>> DiG 9.3.4-P1.1 <<>> mx example.com
    ;; global options:  printcmd
    ;; Got answer:
    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60662

    ;; ADDITIONAL SECTION:

    host `hostname`
    Code:
    mail-1.example.com has address 10.1.200.14
    Any help would be appreciated.

    Thanks

    Default same issue here

    We are network edition and having the same problem as described here. Continuing to work with support but no luck so far. Not able to send mail with TLS or SSL, but can POP with SSL fine. Mailman server also cannot connect to Zimbra with same "lost TLS" issue. Using Thawte commercial certificate and supplied CA root cert file, also have followed this article about "too many files":

    Error (MTA): Unable to set STARTTLS - Zimbra :: Wiki

    Continue to see this error:

    Aug 3 04:07:19 mail postfix/smtpd[3038]: warning: network_biopair_interop: error writing 8192 bytes to the network: Connection reset by peer
    Aug 3 04:07:19 mail postfix/smtpd[3038]: SSL_accept error from localhost.localdomain[127.0.0.1]: -1
    Aug 3 04:07:19 mail postfix/smtpd[3038]: lost connection after STARTTLS from localhost.localdomain[127.0.0.1]

    Suspect that we have same issue as this post:

    TLS-Connection - Broken Pipe network_biopair_interop

    Anyone having any luck?

    Default solved our issue from above

    If you followed this post which has a trick to use the curl root certs bundle:

    http://www.zimbra.com/forums/newrepl...uote=1&p=80428

    that may be your issue. See post at the bottom of that article to see if it matches your situation.

    Not so sure, but over SSL or TLS authentication is necessary before delivering emails.
    May be this is your issue
