Ortime ?†? configuration file (deprecated)
-ortime ?†? command line (deprecated)
Prior to V8 sendmail, only a single time could be specified that set the timeout for all SMTP
transactions. Beginning withV8 sendmail, a list of keyword and value pairs can be specified
that set a wide assortment of timeouts.* In this section, we focus on the current syntax. The
recognized keyword words are listed in Table 24-25. The default and minimum value for
each is described in the individual section. The minimums discussed in the subsections that
follow are those recommended by RFC1123, Section 5.3.2, but they are not enforced.??
* When the argument to an m4 define command contains one or more commas, that argument should be
enclosed in two single quotes.
?? Note that the defaults are intentionally higher than the recommended minimums. Setting timeouts too low
can cause mail to fail unnecessarily.
