Dada Mail 2 10 9 alpha 1 has been released I really need some feedback on this new version, specifically the new SMTP engine

Here's the direct URL to the download:

http://prdownloads sourceforge net/mojomail/dada-2_10_9_alpha tar gz? download

Here's the Changelog:

2 10 9 alpha 1 Changes/New Features There's a new choice on how to send email - more specifically there's now two ways to send messages via SMTP - the old way is using Mail::Bulkmail - sometimes this method is problematic, so you have a second choice: Net::SMTP Net::SMTP also supports CRAM-MD5 SASL authentication and even SSL/TSL connections

More information on how to use this and the differences between the two versions is located in the General FAQ (below)

And here's more information on the new SMTP Engine powered by Net::SMTP and about both the old engine, powered by Mail::Bulkmail

What's are the differences between the two SMTP Engines? Mail::Bulkmail was the original SMTP engine for Dada Mail Net::SMTP is a newer (to us) choice They do a similar job in fairly different ways

Benefits of Mail::Bulkmail:

• Can send more than one message per SMTP connection Connecting to an SMTP server does takes a little time (could be seconds) Multiplied by a list of thousands of email addresses, this time may add up So, if you find that you need a very speedy delivery, maybe look at using Mail::Bulkmail as the backend

• Supports multiple tries at connecting to an SMTP server Instead of completely stopping a mailing because it cannot connect to the SMTP server, Mail::Bulkmail does have the option to attempt an SMTP connection more than once The Net::SMTP engine will simply fail at delivering the message (currently)

Although, if Mail::Bulkmail does reach its limit of connections per sending to your entire list, sending will halt entirely In the Net::SMTP engine, if a message cannot be sent out because of a connection not being established, that specific email address will simply be skipped

Disadvantaged of Mail::Bulkmail

• Multiple connections may not work well with your SMTP server There seems to be some problems with this very feature (as been reported to me) It seems to not always work and the entire delivery of a mailing list message to your subscription list may fail half way when Mail::Bulkmail miscommunicates with the SMTP server

• Bolted on SASL authentication SASL authentication - basically a way to authorize access to an SMTP server isn't a part of Mail::Bulkmail but was added to the engine by the developer of Dada Mail It does not support as wide of a range of different authentication schemes as the other choice, Net::SMTP does It's also probable that the robustness of SASL authentication via Net::SMTP engine is much better as well

Advantages of Net::SMTP

• Good SASL Support Out of the box it should support, PLAIN, AUTH PLAIN LOGIN and CRAM-MD5 authentication schemes Mail::Bulkmail has been tweaked to include SASL support, but only the, PLAIN version

• SSL/TLS support Net::SMTP support sending via port 465 on a secure sockets layer connection

You will need to manually make sure the, IO::Socket::SSL CPAN module is installed on your server - there isn't really a way to bundle it in the Dada Mail distribution

• Net::SMTP widely used The Net::SMTP engine is more widely used in Perl applications than Mail::Bulkmail

Disadvantages to Net::SMTP

• New (to us) The only real drawback, other than the advantage of Mail::Bulkmail of being able to send more than one message per SMTP connection is that Net::SMTP is a very new addition to Dada Mail and as such, hasn't seen much Real World use This may cause unexpected results (erm, "bugs") with taking advantage of this engine Let us know, please!

• SSL support requires IO::Socket::SSL CPAN module You'll need to either have the, IO::Socket::SSL module installed, or install it yourself This module itself requires the OpenSSL library

Long story short, if you were hoping that you can just use SSL connections with Dada Mail - you can, but you'll need a few things already available on your server

• Different Logging Schemes Mail::Bulkmail could be set up with different logs for both errors specifically from mail errors (the, $SMTP_ERROR_LOG) and also something called a, conversation log (the, $SMTP_CONVERSATION_LOG) which would have snippets of the actual conversation between the SMTP server and Mail::Bulkmail These are handy

Currently, any errors reported will be logged into the main Dada Mail Error Log ($PROGRAM_ERROR_LOG) and the $SMTP_ERROR_LOG will not be used at all

A similar feature to the $SMTP_CONVERSATION_LOG is available in Net::SMTP, although this log will still be printed into the $PROGRAM_ERROR_LOG So -

To activate very verbose logging of the SMTP conversation when using when using the Net::SMTP engine, set the Config pm variable, $SMTP_CONVERSATION_LOG to, 1 Please note that sensitive information will be logged, while this variable is set, so DO NOT have this variable set when you are in production

Both engines do support all the other features of sending and SMTP sending: VERP support, batching, etc

Many of the advanced features of Mail Bulkmail including envelop sending and dynamic headers were never supported by Dada Mail, so you shouldn't be missing them in the Net::SMTP engine

• Net::SMTP http://search cpan org/~gbarr/libnet/Net/SMTP pm

Also, look at Net::SMTP::SSL, which handles SSL/TLS connections

Please please please, if you can, give the alpha a test drive and report and problems you may be having,

Cheers,
