    Default TLS not being offered on SMTP after upgrade from 5.0.18 to 6.0.0

    Hi all,

    I have upgraded yesterday from Zimbra 5.0.18 to 6.0.0 (Open Source) on Ubuntu 8.04 64 Bits.

    After the upgrade TLS stopped working, it is not being offered on SMTP port 25:

    SMTP trace before the update (version 5.0.18):

    220 xxx.yyy.com ESMTP Postfix
    EHLO laptop100
    250-xxx.yyy.com
    250-PIPELINING
    250-SIZE 10240000
    250-VRFY
    250-ETRN
    250-STARTTLS
    250-AUTH PLAIN LOGIN
    250-AUTH=PLAIN LOGIN
    250-ENHANCEDSTATUSCODES
    250-8BITMIME
    250 DSN

    SMTP trace after the update (version 6.0.0)

    220 xxx.yyy.com ESMTP Postfix
    EHLO laptop100
    250-xxx.yyy.com
    250-PIPELINING
    250-SIZE 20480000
    250-VRFY
    250-ETRN
    250-AUTH PLAIN LOGIN
    250-AUTH=PLAIN LOGIN
    250-ENHANCEDSTATUSCODES
    250-8BITMIME
    250 DSN

    SMTP/SSL is working fine, as well as POP/SSL and IMAP/SSL.

    Any ideas about what can be the problem?

    Thanks

    Default

    I managed to fix this by running the commands:

    zmprov ms xxx.yyy.com zimbraMtaTlsSecurityLevel may

    postfix reload

    Many thanks cosmo, had the same problem and now it works again.
    You saved my evening

    System: Mac OS Tiger (Mac Mini), Zimbra Network Edition,
    problem appeared after upgrade from 5.0.18 to 6.0.

    couldn't send mails via SMTP, webmail worked, Outlook connectors as well.

    Probably a good idea to fill out a bug report for this one (if you haven't already).

    All the best,
    Mark

    Default Is there a bug report?

    I found this helpful for my TLS on 587 issue, thanks.

    Is there a bug report on it? I can't find it yet and don't want to duplicate needlessly.

    Thanks

    PS Now added one as I'll forget otherwise!
