Authentication required for all mail on Parcom servers




Parcom has always had a standard for mail that has required users to authenticate with the mail server in order to send out messages.

This is even more important today as spammers get more and more creative about how they send their messages.  Many people are infected with viruses and malware that they are completely unaware of.  When someone is unknowingly infected with a virus or malware, their account can be compromised and used to send thousands of spam messages.  This in turn can cause a server to be placed on blacklists, or disabled completely.

At times, Parcom has relaxed the requirements in order to accomodate some older scripts or web design programs.  However, this has allowed others to get around the authentication requirements and opened up the server to vulnerabilities.

SMTP authentication is required to send mail from scripts, and mail clients.   This is the standard.  Relaying on Parcom's servers is not allowed.

In general, for scripting purposes:
Mail must come from your domain - example - mail.yourdomain.com
Mail must authenticate using a valid e-mail address AND password on the server - example - sender@yourdomain.com with the password for this user account
The outgoing mail port can be set to 25 or 587

In regards to mail clients -

If you are on our new cloud hosted servers - the mail client settings are found in cPanel.  We recommend that users on these systems use the SSL settings for their mail client.

If you are on our older Helm or legacy systems - the mail client settings will follow these guidelines regardless of your ISP or client software.
The incoming and outgoing smtp settings are:  mail.yourdomain.com
The userID is the full e-mail address you are sending from.
The password is the one that works with the e-mail address you are sending from
Do not check any SSL settings - they will not work

The following are sually found under advanced settings:
Your outgoing server requires authentication and should use the same settings as your incoming server
The outgoing port can be one of the following: 25 or 2525 or 587.  Some ISPs have restrictions that do not allow some ports to be used.
Remember - do not check any SSL/TLS settings.

These settings will work with most cell phones and tablets as well as computer mail clients.


Security is important to us and so is keeping our servers clean of spam.  If your mail account is ever found to be compromised, we may change your mail password.  We do make every effort to notify you when this has been done so that you can check your computer for viruses and malware.

Thank you for helping to keep mail up and running and keep our servers off of blacklists.
