我使用 sendmail -v [email protected] 从 sendmail 发送邮件< t.txt 但是当我使用 Outlook 或 Gmail 收到邮件时，我会得到额外的奖励!正好 990 个字符之后的字符 https://infoeu.!mytotalconnectcomfort.com 。我不明白为什么sendmail会插入额外的字符! ？

最佳答案
SMTP 协议(protocol)行长度限制
SMTP RFC5321指定消息行最大长度的限制。
Sendmail 会中断长行以避免超出限制。

可供选择的修复:
1.你似乎发送了 html 上下文。您可以使用tidy程序重新格式化您的html。它还应该打破长 html 行。
2. 您可以使用 quoted-printable 编码发送。它对非 ASCII 字符进行编码并处理行长度。
