IMAP-IDLE command is not supported
IMAP IDLE isn't supported at DreamHost. The IMAP daemon they utilize (Courier IMAP) doesn't do IDLE.
Size limit
- Is there a size or attachment size limit for email?
Yes. Our mail servers will reject messages greater than 40 MiB for either incoming or outgoing mail. This limit applies to the entire message size, regardless of content. This means, you can send or receive a message with or without attachment, but the total size cannot exceed 40 MiB per message.
For files larger than this, you should upload the file to an anonymous FTP server or to your website and send the recipient a link to the file.
What is an SMTP server?
It is an Internet email server that knows how to send your email on its way to its proper destination.
In order for your email program on your local computer to successfully send email, it must have an Internet connection plus an "SMTP" server address that it is allowed to send mail through.
When you host with us, mail.yourdomain.com is the address of the SMTP server you use!
What is the name of my outgoing mail (SMTP) server?
Both your incoming and outgoing mail servers are just
mail.example.com
Where example.com is replaced by your domain you host with us.
Also, some ISPs block port 25! You may have to use your ISPs SMTP server instead of ours 'or use the alternate port 587 if this is the case. Your ISPs internal SMTP server’s domain name address is most likely "mail.isp.com" or "smtp.isp.com". You can still have your from email address be @yourdomain.com even if you're using your isps SMTP server fortunately!
Since few ISPs block ports other than 25, use of the alternate port 587 might be better. Especially if you're using a laptop or other portable device that may be used on alternate internet connections, setting the port to 587, will relieve you of changing your settings for each new location.
An additional workaround is to use secure SMTP, if your mail client supports this. See Secure_E-mail for more information on secure SMTP.
NOTE.. you must set your username for the outgoing SMTP server (in Netscape for example under "Outgoing Mail Server User Name) to be the same as your incoming mail server username. It will then ask you for your password the first time you send mail. We use Authenticated SMTP.
NOTE FOR EUDORA USERS: As reported by a user ... "In Eudora each of the personalities needs to have a server specified in the incoming mail section. Even if it doesn't check the email on that account." If you are having trouble sending email from one of your domains, this may be the cause.
Port 25 Blocking
- See Port 25 Blocking
You may need to use port 587 for mail submission, rather than port 25 – see discussion at Port 25 Blocking.
What is the name of my incoming mail (POP/IMAP) server?
Both your incoming and outgoing mail servers are just
mail.domain.com
Where domain.com is replaced by your domain you host with us.
