If you’re using an iPhone or iPad and you see an error message saying an outgoing message “was rejected by the server because it does not allow relaying”, or if you have trouble sending mail but not reading it, this means that your device isn’t sending the correct mail username or password with outgoing mail.

You can fix this in your device settings:

1. Go to the settings screen.

From the iPhone or iPad main screen, tap:

• Settings
• Apps > Mail > Mail Accounts (for iOS 18 or later)
  or Mail > Accounts (for iOS 14-17); Passwords & Accounts (for iOS 12-13); Accounts & Passwords (for iOS 11); Mail (for iOS 10); Mail, Contacts, Calendars (for iOS 9 and previous versions)
• (your email address)

Then tap Account Settings:

2. Verify the “Outgoing Mail Server” settings.

Scroll down the page to the “Outgoing Mail Server” section and tap SMTP:

Then tap the name of the “primary server” (which is most likely marked “mail.tigertech.net”):

Keep in mind that iOS devices have separate sections for incoming and outgoing mail; make sure you’re looking at the settings marked “OUTGOING MAIL SERVER”, not at the “INCOMING MAIL SERVER” settings.

The settings should look like the picture below.

In particular, make sure the following “Outgoing Mail Server” settings are correct:

• Host Name: mail.tigertech.net
• User Name: your email address (all lowercase)
• Password: your email password
• Authentication: Password
• Server Port: 587

Click the Done button in the top right when you’ve finished. Then click Account Settings in the top left to go back one more screen, then click Done again in the top right to save the changes.
