Attachment Size Limit?, How to change the attachment size limit?

Is there a way to change the attachment size limit? I'm not sure what is the current limit, but I couldn't send a 3mb attachment out.

TB doesn't have a maximum attachment size (not that I know of anyway). A more common problem is the maximum message size that ISP's allow for. You should also realize that before sending a file needs to be MIME encoded and that encoding makes the file a good third bigger, so your message would be over 4 MB. My camera averages in pictures about 2.5 MB and when sent the messages are 3.5 MB.

Just some thoughts...
Did you get any error message?
Could it be that your virus scanner locked the file because it was (suspected to be) infected with a virus?
Can you access the file with other applications? And if so, was there an application that claimed sole access to it?

Because this month somebody came with a related question (maximum size to be received) I sent myself a message with a 39 MB attachment, the message thus amounting to 53 MB and that got sent just fine, receiving was no problem either. Both were a tad slow, but that's logical, even on a 100 Mb/s LAN this kind of messages take some bandwidth. Though there was a very noticable lag before TB started the Connection Centre, but I suppose MIME encoding a 39 MB file takes some time.

You can find something that looks like a limit in:
Account -> Properties -> Files & directories -> Message splitting
But that's about splitting the message in parts when it exceeds the maximum message size that your ISP or the receiver's ISP allows for. Note that not all mail clients are able to glue those parts together.

Finally, when you're sending a lot of files around it would be saving a lot of bandwidth to upload those file to your website (as long as you don't place a link on your homepage it'll stay invisible to third parties) and just to mail the URL to your contact.

This is weird. I checked with my webhost. They said my size limit is 10mb. I tried sending a 3mb file which, after encoding you mentioned, became about 5mb+. Its still less than 10mb and when I tried sending, it said Server reports error: Message size exceeds fixed maximum message size.

Is your webhost the ISP you're using to send it? I'm sorry for asking obvious questions, but either they don't know what they're talking about (like receiving limits in stead of sending limits) or you're not using your webhost to send mail.
I once had such a setup, my hosting service offered me a pop3 server for the domain they hosted for me, but in order to send I had to use my ISP.

Yes they are. They gave me a pop3 and smtp server for the domain they hosted for me. And the subject matter is sending limits.

They said the size limit for messages is 10mb, both receiving and sending. Does that clear your doubts? I still do not know where exactly is the problem.

It's a server side problem, as it isn't a TB issue. so I guess you're just out of luck.
You could try it with Outlook Express and then start complaining with your webhost.

I have just confirmed that it is not a server side problem. My webhost told me my size limit for a single mail is 10mb while my size limit for my whole mailbox is fixed at my package size, which is 50gb.

I think the reason lies with the attachment itself. I have tried all kinds of attachments and they worked. The only attachment that did not work was the first one I tried to send. It is an old *.mbox file which I exported out of my previous webhost and was trying to send to my colleagues.

Off hand I can see no reason why the server would react different to a 3 MB .mbox file than to a 3 MB .jpg file.
What about compressing the .mbox with zip or rar before mailing it? That should work.
Another option would be to MIME forward the messages as they are. (Select a bunch of them and select Specials -> Alternative forward)

I was about to say the same thing. ZIP or RAR it. Many hosts check attachments against a mime list and the problem could reside there.

Also I remember one servioe that wouldn't allow ZIP files so you had to rename the sip to (say) XLS and include a note in the email re rename the ending back to ZIP when they detached. Also if you password it that can trip off all kinds of triggers on both ends of the mail route - so don't add a password to your zip or RAR :)

Hmm. The mbox file that I was trying to send is in zip format already. This is getting even weirder. Anyway, I am just curious and wanted to see if there could be any logical reason why this is happening. Thanks dudes for your time in offering an explanation for this phenomenon.
