Javamail api "disk space" problem

Hi,

We have had a class using the javamail api up and running for several years (javamail 1.2). It basically builds an email from various data on the 400 and possibly adds attachment files from the IFS as mime body parts.

A new feature I've developed has ended up creating spreadsheet attachments that are slightly larger than previous attachments (they are only 760kb, but still 200% bigger than anything else we send!) and now the emailer class is receiving a SendFailedException noting insufficient disk space.

javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.MessagingException: 452 4.4.5 Insufficient disk space; try again later
at java.lang.Throwable.<init>(Throwable.java:196)
at java.lang.Exception.<init>(Exception.java:41)
at javax.mail.MessagingException.<init>(MessagingException.java:55)
at javax.mail.SendFailedException.<init>(SendFailedException.java:76)
at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at classes.mail.SendEmail.SendMessage(SendEmail.java:674)
at classes.mail.SendEmail.Send(SendEmail.java:170)

Does anyone know what is meant by " Insufficient disk space "? It doesn't mean actual disk space because the 400 still has well over 1.5 TB to play with, so I was wondering if there is a limit somewhere that maybe a previous programmer set that nobody else here is aware of.

Any help would be appreciated.
