NAME
smtpqer - queue mail for delivery by SMTP

SYNOPSIS
smtpqer [ -nu ] [ -a toaddr ] [ -d domain ] [ -H helohost ] sender host recip ...

DESCRIPTION
smtpqer queues the mail message it reads from standard input for eventual delivery by smtp. The message is queued for delivery to the host specified in the to address.

smtpqer should normally be invoked by the mail command by placing the following line in /etc/mail/mailsurr:

 ´.+´ ´([^!@]+)!(.+)´ ´< /usr/lib/mail/surrcmd/smtpqer %R \\1 \\2´

smtpqer will check the host name in the to address. If it is one that can be reached (i.e., if netdir_getbyname(3) can find it on at least one TLI network), the message will be queued, and smtpqer will exit with a return code of 0 (which means the mail was successfully queued). Otherwise, it will return with an exit code of 1, and the message will not be queued.

Messages that are queued are stored in a file under the SMTP queue directory (/var/spool/smtpq). If the -u option is not used, they are first converted to RFC822 format, by filtering them through the program tosmtp. Finally, smtpqer invokes the smtpsched program to deliver the mail.

The -H option is used to specify the host name that should be used in the SMTP HELO message. This option is passed to both the tosmtp and smtp programs.

The -d option is used to specify the domain name that should be used for your host. This option is passed to the tosmtp program. If this option is not used, and a domain has been specified in the mail configuration file mailcnfg, that domain will be used instead.

The -a option is used to specify the ``to address'' that is passed to the smtp program. Finally, the -n option is used to prevent smtpqer from starting an smtpsched process to deliver the mail.
