Inbound Email configuration / no connecting to the server

Hi all,

We had have upgrade our Sugar instance from Version 8 to Version 9.0.5.
All requirements are set. SugarCRM is running on a Windows server, IIS Web server, Database is Oracle 12c, PHP 7.1.23

Since the upgrade the handshake to the email-server can not established anymore. The error comes from a CRM Plugin called Laminas-mail, which was brought new in one version between 9.0 and 9.0.5.

Connection (via cURL) from CRM Webserver can be established. Password, User name are valid, also Server name and port.

Sugar Support can not help and suggested to ask the dev club.

I am a bit lost right now. Is there someone which faced the same or similar issues?

Any help would very much appreciated.

Thank you!
Rene

  • We recently had a similar issue (but not exact) with an email plugin and not connecting when credentials were correct.  Ours was related to the certificate at Sugar that was updated 2/21 but we were not made aware so as we have a slightly older OS, this issue would not let us use the plugin.  It has since been resolved when we aligned the updated certificate.  Just a thought.

  • Hi David, Thank you for your response. Maybe a stupid question. From what kind of a "certificate at Sugar" are you talking? We're working on a On-premise instance. Our Windows server is on the required version.

  • Hi David,

    Thank you very much for the hint with the certificate. It pointed us at the end to the php.ini.

    Since the patch to 9.0.5 a feature has taken place. There were changes in the "Email and connector security"

    With this Version this "Laminas" Plugin has been new in the package. On our side a change in the php.ini was needed. This was not mentioned all all.

    Before 9.0.5, we defined the path for the certificate file only for "curl.cainfo". Since version 9.0.5 it is also needed to define the certificate file for the "openssl.cafile" parameter.
    This fixed it, an all works fine now.
