Hello,
To add information to this problem, it appears that spamd does
eventually give up after 5 minutes - which then bounces the message back
to the sender stating:
421 SMTP incoming data timeout - message abandoned
Obviously, this cannot keep happening, but i don't know how to stop it...
Any advice greatly appreciated.
Thanks again,
Richard.
