The first section in netMail's Mail Sending Preferences is where you specify the name and email address to be used on all email sent from netMail. Note that he outgoing email address you provide here does not need to be the address that you're logging into netMail with, but if you set it to another address, any replies will go there.
If this mailbox recieves mail for more than one address, you will want to include those other addresses as aliases for this mailbox.
For example, Jimbo has both the .com and .net versions of his domain name, damnfunny, and receives mail at both. He logs into netMail using the .com version of the domain name. If he receives a message that's addressed to "firstname.lastname@example.org" and replies to all recipients of the message, his address will appear in the recipient list.
To avoid this behavior, he will have to add the "email@example.com" address as an alias.
By default, only a single "To" field is displayed when composing messages. You can change this default to also allow you to enter "Carbon-Copy" addresses (Cc) as well as "Blind-Carbon-Copy" (Bcc) addresses. Recipients can see "Cc" addresses but they won't be able to see other "Bcc" addresses.
Many people enjoy writing HTML messages because it gives them control over certain typesetting and formatting features that many popular email clients support. However, sending HTML messages will make your messages twice as large, thus they will take longer for your recipients to download. If your contacts have expressed a desire not to receive HTML mail, then netMail will strip formatting for you automatically when sending. The rich editor is only available for newer full-featured web browsers; If your web browser does not support the rich editor, you will use the plain editor automatically.
Many other IMAP clients can be configured to store your sent-items into an IMAP folder. For compatibility with these systems, you may have to tell netMail which folder to use.
You can have netMail automatically spellcheck your email when sending.
A signature adds a personalized touch to your email messages, and are often used to provide additional contact information to your recipients.
