Hello All,
I am maintaining a server and I use pine as MUA and sendmail as MTA. Suddenly many users in the network face the problem of not being able to attach files using pine. I checked the sendmail.cf file and found a variable "MaxMessageSize = 1000000". Eventhough the message size (i guess it is the message body + attachment if any) is assigned to be 1Mb, I cannot attach even a 100Kb file. I would like to know if there is any way to configure the attachment size? or is there anything else I need to look into. Any help help is greatly appreciated and thanks a zillion. 
What sendmail error is showing in your syslog or maillog file?
Hello kduffin,
Thank you so much for your response. I think the problem is solved. It was just that a partition was full and the mqueue happened to be in that partition, I moved some accounts to nother partition and the problemos was solved. Thanks again.
