Golang : dial tcp: too many colons in address
Encounter this error message Golang : dial tcp: too many colons in address ssl://smtp.googlemail.com:465 while working on the transaction email portion today.
After some debugging, found out that Go doesn't like anything more than 1 colon in a string for hostname and password
To fix the problem, just close the string with brackets.
from
smtpHost := "ssl://smtp.googlemail.com"
to
smtpHost := "[ssl://smtp.googlemail.com]"
Basically, when dealing with hostname, password, and dial function. The rule of thumb is
[user:pass@hostname]:portnum
