Hello I have a truly annoying and urgent problem with sendmail. Particularly bigger mails containing attachments cannot be delivered. They always end up sitting around in the queue with I/O errors, after unsuccessful attempt of delivery. On the system, there are many sendmail processes up, yet there is no activity towards the internet.
