Our Mail Servers can receive attachments as large as 100 mb - the maximum allowed by our Barracuda Spam Filters; however, we highly recommend that some other method of transfer be used when exchanging files larger than 5 MB.

Maximum size for sending an attachment varies from server to server, for example Alentus "SMTP Auth" customers have the following limits:

- Non-compressed Attachment = 5 MB
- Compressed Attachment = 3 MB

See article at http://support.alentus.com/KB/a85/smtp-attachment-size-limits.aspx?KBSearchID=224 for more detailed size restriction information on the various Alentus SMTP servers.
