    Default TLS-Connection - Broken Pipe network_biopair_interop

    Hi,

    we have Zimbra 5.0.2 NE -Edition 64bit running on Redhat 5 EE.

    We have installed a Thawte SSL-certificate. When a customer sends e-mail to us, via TLS, the following error occured:

    Jun 18 04:16:10 mail postfix/smtpd[10044]: connect from mailix.xxx.xxx[212.202.xxx.xxx]
    Jun 18 04:16:10 mail postfix/smtpd[10044]: setting up TLS connection from mailix.xxx.xxx[212.202.xxx.xxx]
    Jun 18 04:16:10 mail postfix/smtpd[10044]: warning: network_biopair_interop: error writing 8192 bytes to the network: Broken pipe
    Jun 18 04:16:10 mail postfix/smtpd[10044]: SSL_accept error from mailix.xxx.xxx[212.202.xxx.xxx]: -1
    Jun 18 04:16:10 mail postfix/smtpd[10044]: lost connection after STARTTLS from mailix.xxx.xxx[212.202.xxx.xxx]
    Jun 18 04:16:10 mail postfix/smtpd[10044]: disconnect from mailix.xxx.xxx[212.202.xxx.xxx]

    The problem is not only 1 customer, all TLS-E-Mails run into the same problem.

    Who can help me? Anybody has some advice for me?

    Default same problem on 5.0.13

    we changed from a self signed ca to thawte, and shortly thereafter, users started noticing that they were not recieving external emails...

    help!

    Default same issue here

    We are network edition and working with support on this problem, to no avail so far. Was it ever resolved for you? Here is another related thread with more information:

    Default solved

    Ours was solved by obtaining the official root CA from Thawte instead of pointing to one in the curl-bundle. Doing that caused a problem when writing the certificate for the MTA. Once we started over with our cert from Thawte, their official root cert (which they will paste to you right in a support chat) and our key, we were good to go after redeploying the cert.
