MM tries to connect to object 125 for SMTP when mailing to a VMS-system, and if that fails uses mail-11. The problem is that MM sends the message as one single DECnet packet, and my QIO' buffer overflows with DATAOVERRUN if the message is larger than the buffer. How shall I do to read from the DECnet-channel less than a full packet..? Cheers, Matts Kallioniemi KOMunity Software AB, Stockholm, Sweden
