当邮件收件人为多人时报错 resp:554 Transaction failed: Illegal semicolon, not in group

[JimmyTinsley]

0.0.1版本和0.0.2版本都试过.
当收件人只有一个时, 报警邮件可以正常发出并被接收, 但是当收件人为多个时, alarm会报出如下错误:

resp:554 Transaction failed: Illegal semicolon, not in group

mail-provider这边出现过如下的报错, 但不是每次alarm报错都会同时出现, 所以尚不明确是否相关, 仅供参考

google Transaction failed: Illegal semicolon, not in group这个报错信息, 搜索结果表示是Tos中逗号与分号的问题, 不知是否和/http/mail.go中这一行有关?

mail-provider/http/mail.go

Line 25 in ff5098c

tos = strings.Replace(tos, ",", ";", -1)
