Question

我通过OAuth和IMAP / SMTP在我的iOS应用中使用Gmail。如果我使用另一个帐户虽然SMTP不起作用。我已尝试在自定义域（通过Host Gator）和outlook.com帐户上使用电子邮件帐户。 IMAP工作正常，只是发送失败。我检查了连接记录器并获得以下内容：

我的SMTP设置为：

电子邮件

密码

港口25（也尝试过587）

MCOConnectionTypeStartTLS（也尝试过MCOConnectionTypeTLS）

MCOAuthTypeSASLNone

在sendOperationWithData中：我收到以下错误：Error Domain=MCOErrorDomain Code=30 "An error occured while sending the message."

这是要发送的代码：

  MCOAddress *address= [MCOAddress addressWithDisplayName:currentAccount.name mailbox:smtp_email];

MCOSMTPOperation * op = [currentSMTPSession checkAccountOperationWithFrom:address];
        [op start:^(NSError * error) {

            }

我配置SMTP（在发送操作之前调用），如下所示：

    if (currentSMTPSession == nil) {
    currentSMTPSession = [[MCOSMTPSession alloc] init];
}

[currentSMTPSession setHostname:currentAccount.smtp_server];
[currentSMTPSession setUsername:currentAccount.smtp_email];
[currentSMTPSession setPassword:currentAccount.smtp_password];
[currentSMTPSession setPort:currentAccount.smtp_port.intValue];
[currentSMTPSession setConnectionType:MCOConnectionTypeStartTLS];
[currentSMTPSession setOAuth2Token:currentAccount.oauthToken];
[currentSMTPSession setAuthType:MCOAuthTypeSASLNone]

Answer 1

问题在于连接类型。当我创建帐户时，我保存了使用MCONetService返回的连接类型。在我之前处理代码库的人是保存IMAP连接类型而不是SMTP连接类型。我改变了这个，现在它起作用了。

我也遵循了@DinhVietHoá的建议并删除了checkAccountOperationWithForm:。

SMTP：发送邮件时发生错误
