How It Works
- Send your email through MailChannels Outbound Filtering by configuring a "smart host" in your mail server.
- MailChannels delivers your email to your recipient, removes spam, and manages IP blocklisting on your behalf.
- When we find a spammer in your system, we notify you at an email address you configure.
- To improve our ability to deliver your email reliably, your system needs to tell our system which user, script, or system was responsible for each message.
- A header is inserted in to each message. This X-Auth header often contains the authenticated sender address but can contain any unique identifier which you can use locate the responsible sending entity.
Choose the applicable Mail Server set up guide from the following list of supported MTAs:
If your mail server is not on this list, chances are you will be able to find smart host setup instructions in your mail server's documentation.
Important points to keep in mind:
- Use TLS encryption (do not use "SSL" encryption)
- The host name of the relay server is "smtp.mailchannels.net"
- The user name is the SMTP username we assigned you
- The password is the password we assigned you (Login to your Host Console and navigate to Settings > Account > SMTP Passwords)
- The port is "25" unless disabled, then choose an alternative: 2525, 465 & 587
Once you have completed setting up your Mail Server, move to the next and final step and configure some service monitors in your Host Console. We notify you of potential compromise and abuse by sending email or automated webhook type notification alerts to help keep your system healthy. By removing compromised accounts quickly, spammers are not allowed to continue making SMTP connections outbound and driving up your service invoice with overage charges.
