Organization of sending mail from a web application

Question

gmail

Dear, how should sending letters from the site be organized in general? This refers to standard projects where letters are needed to confirm user registration, send a forgotten password, etc. Do you need to set up sendmail/postfix/exim on the hosting and send through it, or you can use gmail's smtp (there are limits on the number of outgoing messages) or something else? What is the most kosher way these days? How do you solve this problem in your projects?

Answer 2

Because of laziness, I use third-party solutions (specifically Zoho) to raise my sendmail. The disadvantages are obvious - restrictions on the number. Pluses - you don’t need to monitor the performance of this whole thing and set it up, and if suddenly some script goes crazy and exceeds the limits, then their support turns on outgoing at the request, or increases the limits.

Answer 3

My scheme is quite simple - it costs Postfix with DKIMproxy (all outgoing messages are signed with DKIM-Signature and DomainKey-Signature certificates) and DNS (Bind) must have an SPF record (much less risk that your correspondence will end up in the Spam folder for large providers such as Gmail, Yandex, Mail.ru, MSN, Yahoo!)
