Until now we have been using a default code page for English e-mail: ISO8859_1. This is the name which is widely used by Java. However, because some older versions of MS Exchange server have a problem with this designation, we are now using iso-8859-1, which is the MS Windows name for the same code page.
To address difficulties in sending attachments when using TMmail, we recently increased the size of each e-mail capacity from 10MB to 20MB.
This does not mean that users can send 20MB attachments via TMmail. E-mail is quite ineffective in the sending of the files. When you attach a file to an email, the file is converted to a text form (base64). This text form increases the size of each attachment by approximately 30%. Because of this increase in file size, the maximum size of file you can send via TMMail is 16MB.
If you need to transfer larger files between TimeMaker users, you can use send them via a TimeMaker message instead of sending as an email. When sending via a message, you can send approximately 100Mb’s - and it will be sent quickly, even between many users.

How does TMmail delivery work?
Let’s first start with some basic theory. You send an e-mail to x@domain.com. This mail is delivered first to your SMTP server, designated as Server1 in the diagram below. (en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol).
This server will separate the domain (x) from address (domain.com) and will determine to which server the e-mail should be delivered. This server (designated as Server 2 in the diagram below) is in the domain defined as MX record (en.wikipedia.org/wiki/MX_record). It also is an SMTP server.
Your SMTP server (Server 1) will then deliver the e-mail to the server in MX record (Server 2).
