Since we upgraded to 115, most of our PC cannot forward email larger than 5MB to team members. One or two PC can sometimes send without problem but not always. We can press "forward" and the compose new email window comes up as it has always been. But when we press "send", it will stall for a while then responded "Cannot send email". Press "OK" and sometimes it will then respond "Creating email" or something like that. The sequence could be reversed (create first then cannot send). Cannot even save as Draft into the Draft folder on our own manged MDaemon mail server on our local LAN. Thinking it is all due to the forwarded email being too big, tried many many times over weeks checking MD setting, LAN and individual local PC setting but still cannot resolve. Today I tried something completely different. Instead of "forwarding one large email", I tried to attach large attachments like .jpg etc and found that it is the "attachment process" that is causing the problem. If I attach a larger file, say 10MB, it is problem. If I attach several small files, it sometimes go through even the total file size exceed 10MB. The I tried attaching just a few attachments, save to draft folder, close the compose window, re-select the draft email and then add more file. Repeating this several times I managed to be able to save to draft folder on the server and then send out an email of 49.9MB. I keep on playing with it for hours but I could repeat and can only managed to do something like 10MB/11MB. This is still much better than trying to "forward an email" (as attachment or in-line) which we can only do up to about 5MB max. Please help to resole this problem.
