Names dropping out of /etc/aliases

The line limit is likely BUFSIZ which can be 4096
Note the following about setting up mail aliases in /etc/aliases:
*
Mail aliases in /etc/aliases are public. This means that if you set up a mail alias called softball, anyone can send to softball@your-machinename and make use of the mail alias.
*
When the mail is sent, /etc/aliases mail aliases are not expanded. For example, if you send mail to softball@machinename, that's how the mail reads when it is received. The recipients know what the mail alias is, but not necessarily who else is on it.
The format of mail aliases that are created in /etc/aliases is somewhat different from those in .mailrc. Each /etc/aliases alias should use the following format:
*
The name of the mail alias, followed by a colon (
*
The recipients (logins and machine names), separated by commas. Note that the mail alias does not have to be on a single line.
To modify your /etc/aliases file, you must first become root. If root is password protected, you'll need to know the root password.

aliases
aliases(5) File Formats Manual aliases(5) Name aliases - aliases file for sendmail Description The aliases file is an ASCII file that describes user ID aliases that are used in It is formatted as a series of lines in the following form: name: name_1, name2, name_3, . . . The name is the name to alias, and the name_n are the aliases for that name. Each is separated from the next by a new line. Continuation lines begin with white space. Comment lines begin with a number sign (#). You can only assign aliases to local names. Loops are not allowed because a message should be sent to a person only once. After an alias has been applied, local and valid recipients who have a file in their home directory can have messages forwarded to the list of users defined in that file. This is only the raw data file; the actual information pertaining to aliases is placed into binary format in the files and using the pro- gram The command should be executed each time the aliases file changes. This command allows the new changes to take effect. Restrictions Because of restrictions in a single alias cannot contain more than approximately 1000 bytes of information. You can specify longer aliases by chaining; that is, use a dummy name for the last name in the alias, which creates a continuation alias. The database may be distributed in a network by a naming service, such as Yellow Pages or BIND/Hesiod. See the Guide to Yellow Pages or the chapter on Hesiod in the Guide to BIND for setup information.
