| Author | Forum: PowerTCP Mail for .NET Topic: Sending emails with a large number of recipients |

posted March 1, 2021 8:32 PM I have noticed an issue recently when sending a single email to a large number of recipients. I set the mailmessage.to property to the CSV list of recipients I want. This works fine with no errors. However, looking at the trace, I can see that a CRLF is inserted at around 1000 characters in the "to" list. This causes anything after that point to be not be delivered (treated as an invalid address). I have experienced this on multiple types of email servers. Is there a limit to the number of characters in a recipient list? Here is what I am seeing. 250-SIZE 157286400 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250 SMTPUTF8 STARTTLS 220 2.0.0 SMTP server ready 250-SIZE 157286400 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-AUTH LOGIN XOAUTH2 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250 SMTPUTF8 AUTH LOGIN 235 2.7.0 Authentication successful MAIL FROM:<someone@somedomain.com> SIZE=21719 RCPT TO:<HbcGmMgr.2001@somedomain.com> ...
