General DiscountASP.NET mail server information

Mail server hostname
(When configuring your email program, replace "" in the examples below with your domain name.)
  • POP3 server hostname:
  • IMAP server hostname:
  • SMTP server hostname:
POP and IMAP login name
The login name for your POP and IMAP accounts is the full email address, not just the user name. For example, if you create the POP account "," the login name is "" not "user." You must use the full email address as the login name.

Maximum email message size
All incoming and outgoing messages are limited to 30MB, including the size of the attachment.
Note: Even though the server can send and receive email up to 30MB in size, the size of an email you can receive is limited to available space in your mailbox. Email sent from the web server is limited to 2MB in size.

SMTP authentication
The DiscountASP.NET does not support 'Open Relay' SMTP service.  The mail servers use SMTP Authentication to authenticate permission sent through our SMTP (outgoing) server. This means that in order for a user to send an email through the SMTP server they must supply a valid POP3 account and password.  Without this authentication spammers could utilize our SMTP servers to send spam.

You should only access the mail servers using the hostnames detailed above. Accessing them via IP addresses is not recommended. The hostnames will not change, the IP addresses they point to however, could change. Using the hostnames prevents the need to update your settings if the IP addresses of the servers change.
