    We have a Vserver from server4you.de with min 512MB / max 1GB RAM.
    It took me a few nights to find out why smtp-auth width Plesk 8.01 installed doesn`t work.

    It seems, that the auth-process gets kicked because of a memory limit.

    I checked with telnet and used a CRAM-MD5 maker to send the right password string and i get a
    "421 out of memory".

    What the hell?

    I checked the available RAM with a vmemusage script provided by the hoster and it shows 312MB used of 512 available. So that should not be the problem.

    I found this about increasing the "softlimit":

    and this:

    But that didn`t help me, because i can`t find the line or even the right script where i should add/change the softlimit.

    Any ideas?
