    Hi,
    when I run PHP version 5.4 against my mailserver everything runs fine, even if openssl reports:

    $ openssl s_client -connect serverxyz:587
    CONNECTED(00000003)
    139838124345248:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown proto col:s23_clnt.c:794:

    When I set PHP to a higher version, the SMTP plugin stops working and complains about this error.

    How can I fix this? (It’s a shared webhosting system, so my chances to convince the provider to change something is low 🙁

    Thx

    PHP 5.4 and 5.5 should not have a difference. That’s a 5.6+ that might have a problem with invalid server certificate .pem file. Here are more details. Check comments there as well.
    This hack may help you too: https://gist.github.com/slaFFik/c1d7d4249f47da7195fb973109952090

    Hi Slava,

    Ok, so that worked for you. That’s great.

    No, that fix won’t ever be integrated into the plugin. This is a server-side issue that should be fixed and not a plugin issue.

    I insist on that fix from a gist being a temporary solution until the server configuration will be fixed.
