How large can my outgoing email message be? What about the size of any attachments?
Most email providers set limits for the size of an outgoing email message, including any attachments. Additionally, the size of an email message and any attachments actually increases during the encoding process required for communications over the Internet. Usually, email providers limit the size of outgoing email messages and attachments to 10 Mb per email message. This is acceptable for most business communication requirements. Cbeyond sets a message size limit of 20 Mb for its outgoing email messages. Email messages exceeding this limit will be returned, unsent, to the originator of the message.
