Why another e-mail client?

I (the author) spend a lot of time dealing with e-mail, both professionally and privately. Having an efficient e-mail client is essential. Since none of the existing ones worked the way I wanted, I created my own.

emacs is an integral part of my workflow, so it made a lot of sense to use it for e-mail as well. And as I had already written an e-mail search engine (mu), it seemed only logical to use that as a basis.

3.1.2. Complete Expression for Deliverable Email Address

The following regular expression is a deliverable email address:

; Mailbox from RFC 5321, as amended

P E J DEA     = ([A-Za-z0-9!#-'*+\-/=?^_`{-~\xA0-\x{10FFFF}]+
(?:\.[A-Za-z0-9!#-'*+\-/=?^_`{-~\xA0-\x{10FFFF}])|
"(?:[ !#-\[\]-~\xA0-\x{10FFFF}]|\\[ -~])*")@
((?:[A-Za-z0-9](https:///?:[A-Za-z0-9\-]*[A-Za-z0-9])?|
[\x00-\x{10FFFF}]*[\x80-\x{10FFFF}]+[\x00-\x{10FFFF}]*)
(?:\.(?:[A-Za-z0-9](https:///?:[A-Za-z0-9\-]*
[A-Za-z0-9])?|[\x00-\x{10FFFF}]*
[\x80-\x{10FFFF}]+[\x00-\x{10FFFF}]*))*)

In the regular expression DEA, capturing group 1 is the local-part
production, and capturing group 2 is the domain production.

Amélioration du taux de délivrance des messages envoyés par un serveur Postfix

Si vous utilisez Postfix comme serveur de mails et que vous rencontrez un souci d’envoi de mails en nombre vers Orange.

Building a high-performance mail delivery system is one thing; building one that does not knock over other systems is a different story. Some mailers suffer from the thundering herd syndrome: they literally flood other systems with mail. Postfix tries to be a fast mailer and a good neighbor at the same time.
