    Hi after updating to the latest ISPconfig i get this error to one client only. Before i point the finger i would like to know if this is a known issue? i checked and run a diff tool over the backedup one and the new and there is no change in file. The cert using is the one that ispconfig install generated and is valid according to my webmail who uses the same cert.

    Is the error message about arriving or outgoing e-mail?
    Use Internet Search Engines with
    ssl testing mail server
    to find tools to check certificate e-mail server is using.

    Mine was all green already tested everything on my side, but because i update to the latest version i just wanted to make sure that i didnt miss anything on the change that came with the last version (custom config for postfix and dovecotetc). It was SSL mismatch
    on their side.
