iphone - 通过密件抄送发送邮件时 MailCore 中的错误

Question

发送带有收据的电子邮件时，如下所示致:人A抄送:人B密件抄送:personC

这三个人都会收到电子邮件。并且所有收到的电子邮件将在收据字段中显示 personC。正如我们所知，密件抄送联系人 personC 不应显示。为什么会这样？我使用 to、cc 和 bcc 正确设置了 CTCoreMessage。这是 MailCore 框架的错误吗？或者我错过了什么？

提前致谢!

以下是相关代码供大家引用

- (IBAction)buttonSendPressed:(id)sender
{
[self dismissViewControllerAnimated:YES completion:^{
    CTCoreMessage *testMsg = [[CTCoreMessage alloc] init];
    NSMutableArray *mutArrTos = [NSMutableArray array]; // personA
    NSMutableArray *mutArrCcs = [NSMutableArray array];  // personB
    NSMutableArray *mutArrBccs = [NSMutableArray array];  // personC
    NSLog(@"toContactArr :%@",toContactArr);

    if (toContactArr.count>0) {
        for (NSDictionary *dict in toContactArr) {
            [mutArrTos addObject:[CTCoreAddress addressWithName:[dict valueForKey:@"name"] email:[dict valueForKey:@"email"]]];
        }
        NSLog(@"mutArrRecipients : %@", mutArrTos);
        [testMsg setTo:[NSSet setWithArray:mutArrTos]];
    }

    if (ccContactArr.count>0) {
        for (NSDictionary *dict in ccContactArr) {
            [mutArrCcs addObject:[CTCoreAddress addressWithName:[dict valueForKey:@"name"] email:[dict valueForKey:@"email"]]];
        }
        NSLog(@"mutArrRecipients : %@", mutArrCcs);
        [testMsg setCc:[NSSet setWithArray:mutArrCcs]];
    }


    if (bccContactArr.count>0) {
        for (NSDictionary *dict in bccContactArr) {
            [mutArrBccs addObject:[CTCoreAddress addressWithName:[dict valueForKey:@"name"] email:[dict valueForKey:@"email"]]];
        }
        NSLog(@"mutArrRecipients : %@", mutArrBccs);
        [testMsg setBcc:[NSSet setWithArray:mutArrBccs]];
    }

    [testMsg setFrom:[NSSet setWithObject:[CTCoreAddress addressWithName:@"222222" email:@"letibe.xx@gmail.com"]]];
    [testMsg setBody:self.textView.text];
    [testMsg setSubject:self.textField.text];

    DbManager *dbManager = [[DbManager sharedManager] switchDBWithFileName:DBNAME];
    User *user = [dbManager getAccount];
    NSString *account = user.account;
    NSString *pwd = user.password;
    NSString *emailType = user.email_type;
    NSLog(@"user: %@", user);

    NSLog(@"account: %@", account);
    NSLog(@"pwd: %@", pwd);
    NSLog(@"emailType: %@", emailType);


    NSError *error;
    BOOL success = [CTSMTPConnection sendMessage:testMsg server:@"smtp.gmail.com" username:@"letibe.xx@gmail.com" password:@"222222" port:25 useTLS:YES useAuth:YES error:&error];
    if (!success) {
        // Present the error
        NSLog(@"error: %@", error);
    }else{
        NSLog(@"CTSMTPConnection success");
    }

}];
}

阅读SMTP协议(protocol)后。我修改了 CTCoreMessage.m 以删除 header 中的密件抄送地址，如下所示。这样密件抄送地址就不会打印在收件人中了。

CTCoreMessage.m

- (NSString *)render {
CTMIME *msgPart = myParsedMIME;

if ([myParsedMIME isKindOfClass:[CTMIME_MessagePart class]]) {
    /* It's a message part, so let's set it's fields */
    struct mailimf_fields *fields;
    struct mailimf_mailbox *sender = (myFields->fld_sender != NULL) ? (myFields->fld_sender->snd_mb) : NULL;
    struct mailimf_mailbox_list *from = (myFields->fld_from != NULL) ? (myFields->fld_from->frm_mb_list) : NULL;
    struct mailimf_address_list *replyTo = (myFields->fld_reply_to != NULL) ? (myFields->fld_reply_to->rt_addr_list) : NULL;
    struct mailimf_address_list *to = (myFields->fld_to != NULL) ? (myFields->fld_to->to_addr_list) : NULL;
    struct mailimf_address_list *cc = (myFields->fld_cc != NULL) ? (myFields->fld_cc->cc_addr_list) : NULL;
//  struct mailimf_address_list *bcc = (myFields->fld_bcc != NULL) ? (myFields->fld_bcc->bcc_addr_list) : NULL;
    clist *inReplyTo = (myFields->fld_in_reply_to != NULL) ? (myFields->fld_in_reply_to->mid_list) : NULL;
    clist *references = (myFields->fld_references != NULL) ? (myFields->fld_references->mid_list) : NULL;
    char *subject = (myFields->fld_subject != NULL) ? (myFields->fld_subject->sbj_value) : NULL;

    //TODO uh oh, when this get freed it frees stuff in the CTCoreMessage
    //TODO Need to make sure that fields gets freed somewhere
//  fields = mailimf_fields_new_with_data(from, sender, replyTo, to, cc, bcc, inReplyTo, references, subject);
    fields = mailimf_fields_new_with_data(from, sender, replyTo, to, cc, NULL, inReplyTo, references, subject);


    [(CTMIME_MessagePart *)msgPart setIMFFields:fields];
}
return [myParsedMIME render];
}
