Connection "Extra Commands" for Different Hosts

Different hosts may require different "Extra Commands" on the mailbox page connection settings. This handbook entry tries to document them to make it easier for people to use mailhandler.

Dreamhost

While Dreamhost's php doesn't include the necessary imap_open function, you can still access Dreamhost mailboxes by using the /novalidate-cert Extra command with IMAP on port 143. Be sure to use mail.example.com as the domain (not just example.com) and leave the folder as INBOX.

To use with Dreamhost that has your email through GMail use the settings for IMAP GMail below but for extra commands use /ssl/novalidate-cert

DrupalValueHosting

For DrupalValueHosting you will need to use the extra command /novalidate-cert.

BlueHost

Folder: INBOX
Mailbox Domain: mail.example.com
Mailbox Port: 143
Username: yourname@example.com (Note: In the cpanel help pages it suggests switching in '+' for '@'. This didn't work for me.)
Extra Commands: /novalidate-cert

HostGator

For HostGator you will need to use the extra command /novalidate-cert.

Hostmonster

Folder: INBOX
Mailbox Domain: mail.example.com or hostXXX.hostmonster.com, both works for me (for me XXX=228).
Mailbox Port: 143 (IMAP) or 110 (POP3), both works for me.
Username: yourname@example.com
(Note: In the cpanel help pages it suggests switching in '+' for '@' e.g. yourname+example.com. This works for me.)
Extra Commands: /novalidate-cert

Successful tests for Drupal 6.4

Manufrog

Extra commands: /notls

GMail Settings for POP3 and IMAP

Valid set for POP3:
Mailbox Domain: pop.gmail.com
Mailbox Port: 995
Username: your-gmail-account-name@gmail.com
Extra Commands: /ssl

Valid set for IMAP:
Mailbox Domain: imap.gmail.com
Mailbox Port: 993
Username: your-gmail-account-name@gmail.com
Extra Commands: /ssl

Gmail has so called "labels" - nice possibility for emails categorization and/or filtration. I am not sure if labels can be used in mailhandler field Folder: without problems. It worked for me in the past [~2008], but it fails now.

Unfortunately, many providers block ports 993 and 995, including my hostmonster. I had to test it on my home computer.

1and1

For 1and1 (1&1) you will need to use the extra command /novalidate-cert.
