Perfect - SMTP 简体中文
This project provides an SMTP library.
This package builds with Swift Package Manager and is part of the Perfect project.
Ensure you have installed and activated the latest Swift 4.1.1 tool chain.
Please make sure libssl-dev was installed on Ubuntu 16.04:
$ sudo apt-get install libssl-dev
Prior to code with Perfect-SMTP, please feel free to try SMTP command line example by curl.
This command line tool can be helpful to understand the SMTP protocol and the objective server you are going to work with.
To use SMTP class, please modify the Package.swift file and add following dependency:
.package(url: "https://github.com/PerfectlySoft/Perfect-SMTP.git", from: "3.0.0")
Then please import SMTP library into the swift source code:
import PerfectSMTP
Perfect SMTP contains three different data structures: SMTPClient, Recipient and EMail.
SMTPClient object is a data structure to store mail server login information:
let client = SMTPClient(url: "smtp://mailserver.address", username: "[email protected]", password:"secret")
Recipient object is a data structure which store one's name and email address:
let recipient = Recipient(name: "Someone's Full Name", address: "[email protected]")
Using email object to compose and send an email. Check the following example code:
// initialize an email draft with mail connection / login info
var email = EMail(client: client)
// set the title of email
email.subject = "Mail Title"
// set the sender info
email.from = Recipient(name: "My Full Name", address: "[email protected]")
// fill in the main content of email, plain text or html
email.html = "<h1>Hello, world!</h1><hr><img src='http://www.perfect.org/images/perfect-logo-2-0.svg'>"
// set the mail recipients, to / cc / bcc are all arrays
email.to.append(Recipient(name: "First Receiver", address: "[email protected]"))
email.cc.append(Recipient(name: "Second Receiver", address: "[email protected]"))
email.bcc.append(Recipient(name: "An invisible receiver", address: "[email protected]"))
// add attachments
email.attachments.append("/path/to/file.txt")
email.attachments.append("/path/to/img.jpg")
// send the email and call back if done.
do {
try email.send { code, header, body in
/// response info from mail server
print(code)
print(header)
print(body)
}//end send
}catch(let err) {
/// something wrong
}
- client: SMTPClient, login info for mail server connection

We've received a lot of requests about google smtp examples, Thanks for @ucotta @james and of course the official Perfect support from @iamjono, this note might be helpful for building gmail applications: smtps://smtp.gmail.com
, and you may need to “turn on access for less secure apps” in the google settings.*
Please check the SMTPS code below, note the only difference is the URL pattern:
import PerfectSMTP
let client = SMTPClient(url: "smtps://smtp.gmail.com", username: "[email protected]", password:"yourpassword")
var email = EMail(client: client)
email.subject = "a topic"
email.content = "a message"
email.cc.append(Recipient(address: "[email protected]"))
do {
try email.send { code, header, body in
/// response info from mail server
print(code)
}//end send
}catch(let err) {
/// something wrong
}
