By default, SmarterMail email accounts have a message size limit of 10MB. However, it's important to consider that when a message is sent, mail servers automatically MIME encode the message, which increases its size by approximately 35-40%. To allow users to send 20MB messages, it is recommended to set the maximum message size to 25MB.
To increase the maximum email size for inbound messages at the system level in SmarterMail, follow these steps:
Step 1: Login to SmarterMail as the system administrator.
Step 2: Click on the "Settings" icon.
Step 3: In the navigation pane, click on "Protocol Settings".
Step 4: Select the "SMTP IN" tab.
Step 5: Enter the desired maximum size for incoming messages in the "Max Message Size" field.
Step 6: Click "Save" to apply the changes.
To increase attachment size message that a user can send at the domain level in SmarterMail, follow these steps:
Step 1: Click on the "Domains" icon.
Step 2: Select the desired domain in the navigation pane.
Step 3: On the Configuration menu find the “Limits” tab.
Step 4: Enter the desired maximum size for outgoing messages in the "Max Message Size" field.
Step 5: Click "Save" to apply the changes.
Congratulations! You have successfully increased the maximum attachment size in SmarterMail. Adjusting these settings may affect storage and bandwidth, so ensure your server can handle larger sizes. Consider the recipient's storage and ISP data usage when sending large attachments, use alternatives like FTP or file-sharing services to bypass attachment limits and enhance the experience for both parties.
That’s all.
