hi,

I'm trying to relay a message through Xeams. All works well, until I try to include an attachment (3.8mb). The msg goes through SMTPConversation but I never see it in SMTPOuboundConversation. SmtpConversation reads (for a msg with an attachment):

what could be the reasons for the messages not sending with attachments? I have another xeams server setup, and this one is working just fine

any help/ideas greatly appreciated!

thanks,

adrian
