Hello Yutaka, This is a redefinition of my problem with more details and log. I'm using delegate as an SMTP proxy (to handle TLS) on Win 2000 Server using the : dg9_5_3 STLS=-fcl -P25 -vd SERVER=smtp://127.0.0.1:2525 PERMIT=smtp:*:* ADMIN=peska@mydomain..gr As you see it connects to the same server on port 2525 where ASSP (antispam proxy) listens It works fine, but, some times I have a dg9_5_3 sub-process that never closes. The sub-process works fine until the time it starts receiving the e-mail. >From that point, sometimes it stops writing to the log file and stays active for ever. Note that when this happens, the connection is in SSL mode (using STARTTLS) Some other times it starts writing the following log entry millions of times generating huge log file : (WIN) 25:39.921 [1984] -- SOCKET recv(22)=-1 error=10054 [0.000] Do you have any idea what could cause this error and behavior?
