SMTP: Maximum Number of Recipients Allowed

ID: Q112761

The information in this article applies to:

Microsoft Mail Gateway to SMTP, version 3.0

SUMMARY

The Microsoft Mail Gateway to SMTP has no maximum number of recipients per mail message. The gateway processes as many recipients as it has available memory. In testing the gateway before release, the mail messages sent to and from 300 recipients, with 420K of RAM available before starting the gateway, was successfully accomplished.

The number of addresses varies depending on:

amount of free RAM

size of the addresses, longer addresses take up more memory

number of users on the gateway postoffice

number of Microsoft Mail postoffices defined on the gateway postoffice

NOTE: The successful test of 300 recipients is well over the 100 specified by RFC 821. Also note that many mail hosts on the Internet may not support more than 100 recipients.

MORE INFORMATION

As the recipient list goes over 1000 characters, the gateway continues the list with the next 1000 characters, using the line wrap standard described in RFC 821.
