don't know issue. thing can think of 2 delimiters appended @ end of email can't find either when happening.

this file responsible of sending parts and, attaching separator delimiter.

- (bool)sendparts {     nsmutablestring *message = [[nsmutablestring alloc] init];     static nsstring *separatorstring = @"--skpsmtpmessage--separator--delimiter\r\n";      cfuuidref   uuidref   = cfuuidcreate(kcfallocatordefault);     nsstring    *uuid     = (nsstring *)cfbridgingrelease(cfuuidcreatestring(kcfallocatordefault, uuidref));     cfrelease(uuidref);      nsdate *now = [[nsdate alloc] init];     nsdateformatter *dateformatter = [[nsdateformatter alloc] init];      [dateformatter setdateformat:@"eee, dd mmm yyyy hh:mm:ss z"];      [message appendformat:@"date: %@\r\n", [dateformatter stringfromdate:now]];     [message appendformat:@"message-id: <%@@%@>\r\n", [(nsstring *)uuid stringbyreplacingoccurrencesofstring:@"-" withstring:@""], self.relayhost];      [message appendformat:@"from:%@\r\n", fromemail];       if ((self.toemail != nil) && (![self.toemail isequaltostring:@""]))     {         [message appendformat:@"to:%@\r\n", self.toemail];     }      if ((self.ccemail != nil) && (![self.ccemail isequaltostring:@""]))     {         [message appendformat:@"cc:%@\r\n", self.ccemail];     }      [message appendstring:@"content-type: multipart/mixed; boundary=\"skpsmtpmessage--separator--delimiter\"\r\n"];     [message appendstring:@"mime-version: 1.0\r\n"];     [message appendformat:@"subject:%@\r\n\r\n",subject];     [message appendstring:separatorstring];      nsdata *messagedata = [message datausingencoding:nsutf8stringencoding allowlossyconversion:yes];      nslog(@"c: %s", [messagedata bytes]);     if (cfwritestreamwritefully((__bridge cfwritestreamref)outputstream, (const uint8_t *)[messagedata bytes], [messagedata length]) < 0)     {         return no;     }      message = [[nsmutablestring alloc] init];      (nsdictionary *part in parts)     {         // checking contains actual part avoid appending separators         if ([part objectforkey:kskpsmtppartmessagekey]){             if ([part objectforkey:kskpsmtppartcontentdispositionkey])             {                 [message appendformat:@"content-disposition: %@\r\n", [part objectforkey:kskpsmtppartcontentdispositionkey]];             }             [message appendformat:@"content-transfer-encoding: %@\r\n", [part objectforkey:kskpsmtppartcontenttransferencodingkey]];             [message appendformat:@"content-type: %@\r\n\r\n", [part objectforkey:kskpsmtppartcontenttypekey]];              [message appendstring:[part objectforkey:kskpsmtppartmessagekey]];             [message appendstring:@"\r\n"];              [message appendstring:separatorstring];         }     }      [message appendstring:@"\r\n.\r\n"];      nslog(@"c: %@", message);     if (cfwritestreamwritefully((__bridge cfwritestreamref)outputstream, (const uint8_t *)[message utf8string], [message lengthofbytesusingencoding:nsutf8stringencoding]) < 0)     {         return no;     }     [self startlongwatchdog];     return yes; } 

when that's logged (at nslog(@"c: %@", message);), 2 final separators aren't there.

anyone has hint?

as supposed, issue there additional separator wasn't needed @ , hence failure.

so, on sendparts method, changed this:

[message appendstring:@"content-type: multipart/mixed; boundary=\"skpsmtpmessage--separator--delimiter\"\r\n"]; [message appendstring:@"mime-version: 1.0\r\n"]; [message appendformat:@"subject:%@\r\n\r\n",subject]; [message appendstring:separatorstring]; 

to this:

[message appendstring:@"content-type: multipart/mixed; boundary=\"skpsmtpmessage--separator--delimiter\"\r\n"]; [message appendstring:@"mime-version: 1.0\r\n"]; [message appendformat:@"subject:%@\r\n\r\n",subject]; 

basically, removing [message appendstring:separatorstring];

and then, on loop:

for (nsdictionary *part in parts) {     // checking contains actual part avoid appending separators     if ([part objectforkey:kskpsmtppartmessagekey]){         if ([part objectforkey:kskpsmtppartcontentdispositionkey])         {             [message appendformat:@"content-disposition: %@\r\n", [part objectforkey:kskpsmtppartcontentdispositionkey]];         }          [message appendformat:@"content-transfer-encoding: %@\r\n", [part objectforkey:kskpsmtppartcontenttransferencodingkey]];         [message appendformat:@"content-type: %@\r\n\r\n", [part objectforkey:kskpsmtppartcontenttypekey]];          [message appendstring:[part objectforkey:kskpsmtppartmessagekey]];         [message appendstring:@"\r\n"];          [message appendstring:separatorstring];     } } 

i moved separatorstring top of appending operation:

for (nsdictionary *part in parts) {     // checking contains actual part avoid appending separators     if ([part objectforkey:kskpsmtppartmessagekey]){          [message appendstring:separatorstring];          if ([part objectforkey:kskpsmtppartcontentdispositionkey])         {             [message appendformat:@"content-disposition: %@\r\n", [part objectforkey:kskpsmtppartcontentdispositionkey]];         }          [message appendformat:@"content-transfer-encoding: %@\r\n", [part objectforkey:kskpsmtppartcontenttransferencodingkey]];         [message appendformat:@"content-type: %@\r\n\r\n", [part objectforkey:kskpsmtppartcontenttypekey]];          [message appendstring:[part objectforkey:kskpsmtppartmessagekey]];         [message appendstring:@"\r\n"];     } } 

this solve issue!
