in reply to Most reliable mail module
I prefer to use MIME::Lite for generating the email itself and Net::SMTP for sending the email. MIME::Lite for me is a no-brainer because it makes it totally painless to add attachments, etc. I like to use Net::SMTP when it comes to actually sending the mail for a few reasons:
- better error handling - you are controlling the SMTP exchange so if there are any errors anywhere in the process you can handle them exactly how you want to (you can switch to a fallback mailserver, queue the message for later, or something else).
- significantly faster than forking off a sendmail process.
