I don't know twisted or POE, but the way I handle it is this: - my mod_perl app inserts a row into my 'mail' table, with the name of the mail to be sent, the recipient, and any relevant data - I have a cron daemon in perl, which I've written using Schedule::Cron which loads all the relevant modules that I need. - It fires a job every minute, looks at the mail queue, and uses the local sendmail to inject the mail into the local mail queue, and marks the mail as sent Advantages: - my mod_perl process can return immediately - the cron daemon can run on any machine, doesn't have to be a webserver. - the SMTP server I use (postfix) does just SMTP and does it well, so I don't need to think about networking issues - I have full access to all my perl objects within the cron daemon, and, like mod_perl, the code is all preloaded, so that forking the new job is quick. If a particular job needs some memory hogging modules eg PDF2::API, I require those only in that job, so that the memory gets released as soon as the job is complete Disadvantage: - you can wait for up to a minute before the mail gets processed. Although, with Schedule::Cron, you can schedule jobs every second Clint
