Golang : dial tcp: too many colons in address


Tags : golang email smtp colon

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
