DirectMailDelivery

✓ from repoze.sendmail.delivery import DirectMailDelivery

✗ from repoze.sendmail.delivery import DirectMailDelivery

Sends an email directly via SMTP using DirectMailDelivery and SMTPMailer.

from repoze.sendmail.delivery import DirectMailDelivery from repoze.sendmail.mailer import SMTPMailer mailer = SMTPMailer(hostname='localhost', port=25) delivery = DirectMailDelivery(mailer) from_addr = 'sender@example.com' to_addrs = ['recipient@example.com'] msg = b'Subject: Test\n\nHello!' delivery.send(from_addr, to_addrs, msg)

Debug

Known issues

breakingIn version 4.0, the import path for mailer classes changed. The old repoze.sendmail.mailer module was split into separate classes.

fix

Update imports: from repoze.sendmail.mailer import SMTPMailer instead of the old alias.

affects: <4.0

deprecatedThe use of the 'mailer_factory' function is deprecated. Use DirectMailDelivery or QueuedMailDelivery directly.

fix

Replace mailer_factory calls with explicit delivery class instantiation.

affects: >=4.0

gotchaThe library requires the 'transaction' package for queued delivery. If you don't use a transaction manager, the message may not be delivered until the transaction commits.

fix

Ensure you have a transaction manager (e.g., Zope or pyramid_tm) when using QueuedMailDelivery.

affects: All
