Hello Monk!

After researching the same I came to decision, that it is more convenient to use MailSendmail: it uses the system command "sendmail" and just puts the mail into local MTA queue. The last is responsible for actual settings, mail re-transmission on temporal network failures etc.

In Debian and many other linux distros there is Exim and other MTAs, which almost "just work" out of the box. So, now it is sysdadmin responsibility to setup MTA, not my as developer.

Here is my setting for that

log4perl.appender.Email=Log::Dispatch::Email::MailSendmail
log4perl.appender.Email.to=a@b.com
log4perl.appender.Email.from=c@d.com
log4perl.appender.Email.min_level=warn
log4perl.appender.Email.layout=Log::Log4perl::Layout::PatternLayout
log4perl.appender.Email.layout.ConversionPattern=[%r::%p/%P] %c{1} (%L
+) :: %m%n
log4perl.appender.Email.buffered = 0
