[quote]… Snag: your e.g. "firstname.lastname@example.org" mailbox won’t have login name “fred” as you might have expected. It will have a login name like “m7483986”, which your users may find less easy to remember e.g. for logging in at non-DH webmail.
Workaround: Create the mail address not through panel Mail… but instead through Users | Users | Add New User where you can choose a friendly login name from those not already taken on the DH system. Though this method creates also an FTP user of the same name, if you don’t want this you can delete it using […/ Delete] - check the box for user type ftp box not the box for user Type mail.
How do I send email from my new email address?
In a pinch, you can always just use DreamHost’s free webmail system at your own domain!
If you’d like to use a regular email client, you just need to go to your mail settings and set your from address in your program to be the one you’d like! You should also set your outgoing (SMTP) email server to be mail.yourdomain.com, and if you have an option to specify a port, you can change it from 25 (the default) to 587. Also, be sure to select that “my server requires authentication” and enter your username (most likely m#######-style) and mail password.
You should now be able to send email from your regular email client.
Snag: Most outgoing mail can be intercepted by another user who on his panel has added bogus mail services for external domains he doesn’t own.
Workaround: Use a non-Dreamhost SMTP server. … [/quote]
I think I understand what is happening. I still have a few questions.
Why switch ports for outgoing mail?
Is outgoing e-mail interception something I should worry about?
Why does DH recommend using another service for outgoing mail?
These issues may be present on every host, but this is the first time I have seen them discussed.
Thanks for any help.
