sendmail - large messages only queueing

I’ve got a strange sendmail problem I’ve never come across before…

Messages less that 2500 lines (approx 169kb) are sent correctly - anything else goes straight into the queue and is never delivered. The server sits in a intranet, is not connected to the outside world, and forwards its mail to a smart host.

All configuration has been done through yast, so there are no unusual settings. I’ve run sendmail on SuSE from version 6 upwards, and this is the first time I’ve come across this - it’s driving me potty, can anyone help? :’(

Surely there must be some messages in the log about failed attempts to relay upstream? What do they say? Have you set up the queue flush interval correctly? I assume that you know how to do this since you are a long-time user of sendmail.

And by sendmail, do you really mean the original sendmail, and not postfix with sendmail compatible interface?

That’s the weird thing - no errors, just the entry that the message is queued. The queue should process every 30 minutes (opensuse default).

Yup -it’s sendmail - I removed postfix option during installation, as I’m more used to sendmail.

It’s just down to message size. Doesn’t seem to matter what the data in the message is, if it gets to a certain point, it queues, rather than being processed. The fact that sendmail NEVER ATTEMPTS to send it, would indicate a problem with sendmail (or the config) itself.

I think I’ll try the same opensuse install on a virtual box, and see if the problem can be duplicated…

Tried one last thing - a reboot of the machine…

… and the problem disappeared …
