Here's my problem. I'm having a problem receiving mail from a specific site. They are running NTMail and we are running Qmail 1.03. Mail sent from this site is being returned to the senders after 4 days or whatever. Their log shows repeated entries saying waiting 10038 mailhost.howden.com and mail destined for our site is constantly being deferred. If I watch the connection from our MX, I can see the mail coming down and then the connection seems to be dropped suddenly. The even weirder thing is that some messages seem to be getting through OK. I'm wondering if it's a bare LF problem as occasionally the qmail bare lf error appears in their log file. I'm starting to panic as I'm not sure if this is happening from other sites as well. Can anyone please give me any pointers as this has only started happening after moving from sendmail and I don't really want to go back! Any pointers much appreciated. Simon Rae
